This is an ongoing problem. I have had multiple frame related issues with this 5th wheel RV. The bedroom closet wall separated causing items to fall into the opening, A crack developed that eventually reached 9 ‘ in length in the sidewall by the bedroom slide. Most of the frame gussets supporting the rear and sides of the RV BENT and or the welds cracked. The floor sloped down at the edges due to improper support, Multiple times the propane doors opened while towing, Screws keep unscrewing from around the front of the RV. small cracks in the frame. The main bracket that holds the slide wall to the RV cracked and needed emergency welding while on the road, if it broke completely off the slide would come out while towing! After numerous attempts at getting Grand Design to fix this unit, I had to spend thousands of dollars to prove it was road worthy to tow it from Arizona to Indiana to their service center. They finally agreed to repair it. After 3 weeks we got it back with everything fixed or so we thought, less then 500 miles later the crack in the sidewall came back. After reaching out to Grand Design again they agreed to repair it again, 3 weeks later it was repair. Now the Wall the they repaired is moving, obviously something broke again. From the looks of it they didn’t fix the problem just covered it up. The supports under the floor are bent and I had to put a 2×4 to support the floor, never fixed. We are full time in this RV and it gets towed all over the country. I have tried to reach out to Grand Design again for repairs but have been rebuffed in my attempt. This RV has been nothing but a disaster, having replaced a bent axle, numerous leaf springs and brakes. This RV was sold stating it was for Full Time living, we will attest that is not the case as they are not built well enough to sustain towing on the roadways of the U.S.A and Canada.
