Take a good look at the carrying capacity of the Grand Design. A few of the big boys I looked at had very low cargo capacity. I have a 2015 GD fifth wheel and it's a smaller model (27RL). It has had it's share of small issues but GD has always sent me the parts I needed. Also be aware that GD uses Lippert axles and there has been a big issue with grease leaking from the hubs(GD isn't the only RV manufacturer with this problem either). Lippert changed manufacturing methods and axles built after 5/8/17 are now packed with red colored grease. If you buy a new GD, check the manufactured date which will be imprinted on the axle. Lippert has been paying RV dealers to inspect and replace greased brakes prior to delivery.
