I would like to know how to slow down this teeter totter action I get while going down the road. It gets bad at times were the t.v. speakers will come loose from the cabinets. Any suggestions ? I have a dodge 2011 3500 hd 4 wheel drive . The 5er is a alpine made by keystone its 39 ft . 2012 I travel with no water, the weight is 13, 500 lbs loaded, not maxed out. The hitch is located over the rear axle. When pulling the trailer the truck doesnt bounce up or down. I notice the pin box doesent move. It the body of the trailer. You can see were the body rubs on the pinbox as it teeters up and down, when it gets bad.
I have 2012 5er made by keystone its a alpine. I had the same problem with the bedroom silder. Mine would come out about 1lnch at the bottom. First time dealer changed out the hyd pump, they said they fix it. Ipick up the trailer and as I drove home the slide came out. The dealer then change the manifold still didnt help. It took 3 pump and a manifold to get right. The dealer towed the trailer 30 miles and the slide never came out. I then came down and pick up the trailer and took it home about 65miles. I havent taken the trailer out yet. Good luck, it took 3 hyd pumps to get it right for now.
