We decided to buy another Grand Design RV after our first GD was so well built. Man, a lot has changed! From the day we bought the RV there has been nothing but issues. The dealership has had it more than 7 months of the last 14 months. 3 of the 4 four brakes didn't;t work the day we bought it, but the dealership told me to go buy a fuse for my truck and sent me on my way. From the beginning our list of issues included;
Front door not closing correctly
garage entry door not closing correctly
marker lights not working
rear brake light intermittent working
gas fill station won't take gas
tears in roof
bubbled out wall panels
electrical outlet not mounted propoerly
trim falling off
trim not cut to correct length
seem tape coming off on various walls
shower rail not caulked at all and leaking water
caulk hardened in sink
Front door let light pass through the door because they're was no foam in part of the door.
Under rear of garage metal is already rusting
stair rail was loose on inside
stair rail on outside rusted
Those were just some of the issue, but we had to have them repaired multiple times. The fuel station still doesn't fill correctly, and we have had to bring it back many times for repairs to be redone.
While the repairs are a problem with the dealership, GD has done little to nothing to make things right. Where as we used to be big fans of GD, we will be looking at other brands now for our next RV.

We received our special order grand Design 350 G two months before it was supposed to be ready. Picked it up at Lazy Days RV in Tampa Florida. We were walked through with maybe 15 minute show and tell how everything works. The couch was not what we ordered and we're told it was a mistake. Everything thing else seemed in order from the generator to the solar panels. Get home with our brand new camper and started cleaning it the next day. It was filthy. Took 2 days to clean and couldn't believe the damage. Looks like some one lived in it. Cracked cabinets, sinks and countertops deeply scratched. Some of the valances had only 1 bracket and were an inch away from the wall. Couldn't even open the recliners because of it. Seals on slides you can see thru. Called Lazy Days and sent photos 2 times. Never got a response!!!!! DON'T BUY FROM LAZY DAYS!!! And GRAND DESIGN company is going down hill fast. !!!

This is absolutely the best built 5th wheel toy hauler on the market. We have owned 3 & no comparison. The insulation,the heated tanks,the race track circulation A/C,the patio,the awnings,the led lighting,etc.there's so many standard options that you have to add on with the other brands.we were completely blown away. We are selling this unit in hopes someone else can take advantage of all the space it has. The 2 of us & our motorcycles don't need all the space. We have installed removable chocks for towing the bikes.
