We are on our first trip in our new to us 5th wheel. We have a 07 toyota tundra 4 door 4 wheel drive with a 4.7 v8 engine and a 1995 24 ft sandpiper by cobra 5th wheel. We are using a curt slide hitch. This is the first time I have ever had a 5th wheel. Due to the height of the bed of our truck I had to raise the hitch a couple of inches. The trailer doesnt tow level. I noticed on the way down to the Oregon Coast that it was sort of bouncing the truck and didnt really tow very smooth. I noticed it is not towing level. I cant lower my hitch or I am too close to the bed rails on the truck. I am thinking maybe I could raise the two axels by cutting loose the shackel mounts from the frame and use some box beam to raise the rear of the trailer about 4 inches. Has anyone else ever had this problem. We are at a campground now (and by the way if you are a veteran and have any form of military ID some of the campgrounds give a military discount they gave us 18.00 off of 3 nights) so I am thinking that when I get home about cutting the axels free and raising this thing up so it will tow a little more level. I think maybe that would help the bouncing on us and make a smoother ride. I know how to weld and have an arc welder. I was thinking about using some retangular box beam and gusset plates to weld to the frame and then re-weld the shackel mounts to the box beam. Any thoughts? Any help? Has anyone done this before? We love the trailer but it just didnt tow very well. I also noticed that I could watch the gas gauge move as we drove and I was thinking if it towed more level that it may help with the mileage.
