we have had our wilderness 5th since new in 1993. bought it when both kids in mid teens?have done regular maintenance, like everyone appliances repaired,brakes, tires. when we first bought it the dometic fridge had problem with staying lit. Internet in its infancy, but studied for solution. Bought dinosaur board. Now you can get them anywhere,then you had to order it from Oregon, mail order. Today {still in business} still solves problem with dometic fridges.My fridge {original} to 1993 with dino board in it,died last year {2018}. Board still works fridge gave it up.I will probably run into someone that hopefully can use it to solve their problem with fridge.
Didn't help when we were T boned in the trailer in Alabama by a car. I saw it in my rear view mirror, sitting in my truck, and saw it bounce up and leave a wheel mark 24 inches up from the ground. I thought oh man this cant be good.
This a wood constructed trailer and thought there is going to be a big hole. And there wasnt just the wheel mark and no wood damaged or wall flimsy when pushed on. So I too think trailers were definitely built better 25 years ago.
