Toy Hauler with no gravity fill for boondocking. One fill location for city or tank fill under slide out. You haulers are for boondocking not RV parks. Tried to fill water intake with pond pump while boondocking but system filled with air making water system (especially shower) unusable. Called Grand Design... they blew me off rudely telling mr it is my problem. Worse service I've ever experienced.

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.

Have to start by saying we really liked our GD 2800 BH that we traded in for the 28G. No issues. First trip in the 28G we noticed right away that the 30 amp service was going to be a problem. With one AC running, TV and coffee maker we kept popping a breaker. Later tried running the 2 AC’s w only TV on; 88 today here in Orlando, and that kept popping the breaker. Each unit was set to diff temps and one started 10 minutes later than the other. Contacted GD and got right to a service advisor who seemed to agree, the 30 amp service should have really been a 50 amp. It’s really not enough amperage to do what you should be able to do in a 50k toy hauler. Other concern is our ramp door is leaking, it won’t stay down completely when trying to load, maybe just a bad spring? We realize all RV’s have little things that happen. Wife’s biggest concern is the lack of storage, inside and out and of course the 30 amp service. If our truck could have towed a larger Momentum we would have looked at those or a Fuzion by Keystone. All and all we have some buyers remorse and wish we would have done a little more homework, 50 amp, more storage, layout etc...
