If they work so well on mini vans why do they not work on the Rockwoods?
Agreed that they do wear out. Although I've driven numerous vehicles with rear hatches for many years and have only had to replace one in my life.
My previous trailer was a Wildwood with struts under the bed. I almost had to put my entire weight on it to get it to close again after I opened it. So they worked extremely well.
As for the people having trouble, I can only assume their struts are either undersized or wearing out. I can't imagine the beds weigh any more than some of the tailgates the struts hold up.
