As you know Covid has isolated all of us and this camper helped us move around the country to visit our grandkids. The Thor Quantum ran smoothly and flawlessly. Our grandkids and family spent great enjoyable times staying in the bunk beds and roomy accomodations. Using the 5 TV's, HDMI Video Distribution Box, and Cable TV and HD/DSS Satellite Ready really entertained us all.

This is our first RV. We have 2 little kids (2-year-old and 8-month-old) and the layout with bunks is perfect for our little family. We have a few complaints but overall happy with our purchase.
PROS:
Bunks!
Only 33ft long so it's easy to find a spot in all National and State Parks
It's a motorhome, so travel days are actually fun - you can use a fridge, bathroom, and have amazing landscapes outside or your home window!
It's fun to take it to national parks and have picnics there with amazing nature around
Set up is pretty easy with an auto-leveling system
Fairly easy to drive and park
Awesome queen bunk over the cab with large window (our favorite spot in the house!)
Good looking interior and exterior
CONS:
- Very little storage because of the bunks
- Living room is really non-existent
- Narrow walkway leading from the bedroom to the living room (we hit that door with our shoulders all the time)
- Not the best craftsmanship - had to beef up drawers in the dinette and fix a few minor things with cabinetry
- THIS ONE IS FIXED: weak inverter and house batteries. We replaced our house batteries with lithium-ion batteries, got a stronger inverter/converter and 3 solar panels on the roof - now we can camp with no hookups for longer

Over all build quality is awful, construction materials poor and support inadequate. I have decided to upgrade materials as I effect repairs myself. I suggest that getting the seven year warranty ( we purchased this ) is not worth it, we never received the details until after our purchase and were shocked at what little it covers.

Don't buy from Thor! The coach looks great inside and the floorpan is good for a family. Kitchen a bit cramped for regular use and the slide doesn't open as wide as others (probably because it runs the length of the coach). Bathroom is large which is it's saving grace along with a nice residential fridge. Other than the floorpan and how it looks inside we've had nothing but issues in the past year. It's been in the shop for warranty work more than we've been able to take it out on trips. Very very poor quality work. We've had drawers drop the bottoms (with minimal inside), or open while traveling. One of the top cabinets has opened a few times and poured everything on top of our children while driving (been "fixed" at least once). It took months to get the entry door "fixed" because it sticks and it still sometimes sticks. I will say part of our issue has been a horrible dealer service department but if the unit didn't have so many workmanship issues we wouldn't have known how bad the dealer service was. As far as the engine - we took it from Florida to Pennsylvania this past summer. It was rough on the mountains (and they aren't as high as out west) and was struggling. We weren't even towing a car and don't think it could pull one if we tried. Save yourself some heartache and look elsewhere.

We have had an amazing experience with our brand new Thor Quantum LF31 bunkhouse. We have toured Canada Yellowstone most of Utah Nevada and a bunch of other places. Things that we have really enjoyed about the bunkhouse has been to multiple TVs hooked up to the inverter so we can watch TV without the generator. We have liked the residential fridge and icemaker as it has a ton of space. Some of the shortcomings of this coach are the freshwater tank only holds 40 gallons in the black and gray tanks only hold 28 gallons. That has been a little less than what we feel we could have used. The batteries that came with our motorhome were pretty much dead from the factory so we replaced the batteries with four 6V golf cart batteries and have had a great experience with that.
The layout of this coach is great, and sooth our family of five perfectly. The master bedroom is a great escape for me and my wife. We did upgrade the TV sound systems so that we could here and enjoy our movies on the road.
The drivability of this coach is great as it tracks very well and is comfortable to drive even though it is over 32 feet long. We also have loved the on-demand water heater for showers, when hooked up to city water our showers are endless and hot
