Hay Stan .........
I've owned my camper for over a couple years now, and have to admit the first two years were problem free, but now I seem to have made up for lost time.
First of all, I was up at 11,000 feet and noticed my camper had come loose and was moving around the back of the truck. One of the tie-down bolts had pulled out of the wood frame and two others were ready to go. I was able to "Jerry-rig" the unit to get it off the hill. Now it is in the garage and I am revamping the whole tie down system.
What I don't understand is the company prides itself on it's strong, aluminum frames, why then are the tie-downs not attached in some way to the metal frames? The plywood is just not nearly as strong. I admit I take the unit on roads I probably shouldn't but I did my homework and thought your unit would fit my needs, in fact I drove 2,500 miles to pick it up and although it wasn't new (2007 Keystone) it had never been used. I think maybe in the future you should, at least do what I intend to do and add a support of a metal strip running the length of the main camper. In fact, I'm thinking about 3/16 steel on top by the bench seat and underneath where the old tie downs were, and bolt them together. I'm really concerned about it happening again. I'm thinking that should cure the problem.
Maybe for future models you can up-grade the whole tie down system?
