Keystone Cougar Toy Haulers 5th Wheel reviews

We purchased this RV spring 2024 new , never sold til we bought it. We received a email.from Keystone stating the first year warranty was about to expire. So we did a complete inspection and found the rubber roof was bubbling bad . We took photos of this as well photos of other defects and sent them to Keystone. . We had experienced finding water puddles inside the RV in a couple locations. Below where the air conditioner is and between the washer and the pantry opposite the washroom. We took photos of the roof and we'll the interior trim pieces coming off and a few other things and reported it to Keystone. After we took it to the dealer for inspection, the dealer sent in photos the Keystone. Keystone Denise the claim evern though the RV was within its first year of warranty. We had to authorize the dealer to complete all the repairs and asked the dealer to send photos and reports to us and Keystone. The dealers techs found the rubber roof was not installed or sealed properly. Interior panels rotting and mold covered when removed in several areas. Since the repairs are currently ongoing as I write this, Keystone now has offered to cover 10 hrs labour and all the materials. But the original quote was 40 hrs labour and these findings have increased the labour time. If I could post photos of all this on here I would. Wee are going to sue Keystone ass well register complains with consumer affairs. Keystones.warrenty isn't worth the paper it's written on. This is our second Keystone toy hauler RV. Our first qaaa a 2015 Keystone Carbon. It was a really good RV and I wish now we had kept it. Jim and Karen . Very disappointed! Show less

Bought this trailer in 2017 brand new. The day I took possess I had the spot weld the drop down legs as the pull pin was bringing the internals out as well on about every corner. Shower holder fell off wall, wasn’t screwed into anything but the wall board which is very thin. Roller bearings on the roll out trashcan came out, the back of the supports weren’t braces on both sides allowing it to move up and down independent of each side. At the two year mark the converter went out and then the refrigerator cooling unit went out. The roof was delaminating and the nails were coming loose underneath the membrane and trying to poke through. Then the water from snow and rain started seeping under the fiberglass shell. It was nothing but a money pit. The slides wouldn’t always go in evenly and I had to take that for work as well. If you buy one expect to budget another $250 a month for repairs above the monthly payment . I will never buy another keystone product again. I purchased a 1995 Nash that I have had no issues with. What surprised me is the Nash toilet still will hold water unlike the keystone. Show less

This 5th wheel makes me feel like Tom Hanks in The Money Pit. Everyday it is something else. I wonder if Keystone has considered a quality control program. The furnace is out, the water pump pushes the water back out the same way it was put in, the paint is flaking off of the unprimed metal framing around the ramp door, the trim inside the camper has already had to be reinstalled, the locks for the access panels come out when operated, etc. What makes this so sad is the camper was purchased in December 2025, brand new off the lot, and has only been towed for one trip at 600 miles(+/-). And don’t even get me started on the most useless document ever published, the Owners Manual. Most definitely the worst money I have ever spent. Show less

We bought the 2025 Cougar 364BHL Hero edition in June of 2025 and used it through last summer and fall; writing this on 3/10/2026 as we get ready for the next camping season. We are mostly weekenders with 1-2 long distance trips for a week+ each year. This is camper #6 so we've had everything from popup to this fifth wheel and the full spectrum of quality. Bar none this is the best unit we've had. Fit and finish is top tier. All of the mechanicals work fine, from hooking, unhooking, driving, camp setup and enjoying it. Water and sewer systems are fine, although tankless water heater is quirky and takes a bit to get used to. No leaks; I am constantly scowering the roof, walls, floors, plumbing and fixtures for any moisture. Electrical system is great; no issues. Appliances are all great; no concerns. The only warranty concerns were a couple of window shades, one pocket door that was damaged and one piece of trim replaced. That's it. Tows great behind my Ram Truck. So, I do hear horror stories about campers built afer 2019 as having so many issues, but I will say, in our case we have had a really good experience. We purchased it from Camping World in Syracuse, NY and we were very happy with the before and after purchase experience. Show less

When picking up the new cougar fifthwell it would not attach to the slide hitch correctly. It would fit on a short bed truck, but not on a long bed and they didn't know this. We had to have some adjustments made, and it finally worked. The furrion refrigerator freezer never worked even after taking it in a few times to the dealer. A private rv person tells me to do a hard reset, and it should work after that. It works correctly one time and then goes back to its old habits of not cooling and freezing correctly.. we have the lost food frequently because of this. Everything online says that furrion rv refrigerators are nothing but problems. All of the cabinet doors and drawers fly open while driving slinging everything you have onto the floor and that's not while driving on a Bumpy road. The heating floor vents are made out of plastic embrake quite easily. Metal costs a few more dollars and works so much better. The igniter on the furrion stove eventually broke off, because it too was made out of cheap plastic. Show less

** BUYER BEWARE ** To ANYONE looking to purchase a KEYSTONE MONTANA 5th WHEEL, please BEWARE!! We have experienced our THIRD CATASTROPHIC SUSPENSION FAILURE on our Keystone Montana 3790RD 5th wheel which involved the leaf springs snapping for the THIRD time, which then caused the second axle on the unit to be forcefully jammed up into the the chassis causing significant damage to the underbelly of our unit, along with CUTTING OUR BREAK LINES causing us to lose the brakes on our trailer while going down an overpass on a highway. We have been informed by the repair shop that we are EXTREMELY lucky there was not a fatality and that if they repair it, the chances of it happening again are EXTREMELY high and just a matter of time until there is a fatality with the unit. We tried reaching out to Keystone RV and Thor Industries via letter, and all we received was an extremely rude call from the VP of Service Operations, Garrett Carolis, telling us our request for assistance was not warranted and that our letter was an "extremely unrealistic expectation and will not happen." He also said that Keystone RV will NOT financially assist in anyway and that we are "absurd" for even asking. Keystone is also fully aware that I had a PICC line in my arm for IV medication and we were stranded on the side of the road for over 6 hours because of their manufacturing defects. We are still stranded, and have been for almost 2 weeks, in the town we were passing through when the incident happened because the repairs are now up to $10,000 and with the safety warning of taking it back on the road, we are extremely concerned. We just want to make sure ANYONE LOOKING TO BUY A KEYSTONE MONTANA 5th WHEEL is aware of what happened to us and the absolute NIGHTMARE we are dealing with because of the terrible manufacturing of our KEYSTONE MONTANA 5th WHEEL. Please travel safe y'all. Show less

We bought this 42 ft. Fifth wheel brand new at Camper World Riverton Utah. I bought every warranty and extended warranty I could get because I know the quality of most of them. What I didn't realize is that if you need any warranty work it needs to go to the dealer and sit for days or weeks to get a repair and your stuck in a hotel. Even with the DIY program couldn't be any worse for the customer. Our main electrical 50 amp cord shorted out and burned and melted the connection on a Sunday. I went to the hardware store and bought a new plug to get us going. The camper World asked for pictures which I had taken before removal and showed all the damage it caused only to get denied my claim because I didn't bring it in. After calling in a couple of other issues we had and being told it had to come into the dealer I just gave up. We're retired and don't beat our stuff but this rv is no better than the bottom of the line as far as I can tell we spent over $100000. and I couldn't be more disapointed. Our heater is now going out at least the bearings are squeeling. Looking back I would not have bought the best one on the lot (according to my sales snake) and bought something much less and just planned to fix it. I would have saved a ton of money. It pulls good and we like the layout the trim falls off the ceiling after we have towed it for a while so I have been repairing this as we go and it also leaks when we get a solid rain. I wanted to show the wiring under the rig. There is NO pride in the workat all! Show less

Small items to note. Heat in bedroom works best if bathroom door is open as bedroom only has one heat vent. Overhead vents need an extension wand to open and close vents as they are very high up on ceiling. No towel storage in bathroom and only 1 light above mirror making it hard to put on makeup per wife. Smart tv is a pain to get it to connect to cable or antenna. They should add an awning to the rear door area just like the front door. Expanding ladder for rear bed the step is angled wrong making it hard on your feet. Small table for end of couch should be angled cut on one side so it would swivel when getting up. Overall build quality and layout work well. Very happy with our purchase and this is our 3rd Keystone camper. This review is based on 30-day ownership and 2 camping trips. Show less

We lived in this Fifth Wheel for 19 months and went cross country to the Pacific Ocean staying one month visiting family. The RV is roomy and very comfortable. We are trying to sell due to advancing age and inability to travel any longer. Unfortunately there is a loan on it so not a lot of negotiating room. Show less

Our Cougar 5th wheel had a few problems that had to be addressed but it is overall a great camper. It is very easy to tow, easy to set up and easy to live in for extended vacations. I especially like the level system and the slide system. Both have been great. Our issues were the refrigerator ( vent blocked in top), slide cables were out of adjustment and the awning needed adjustment. None of those was major. Show less
