Construction of trailers

Wow I just had a minute to stop by and see what anyone wrote. I try to take the best care of my trailer as I can. If you go the all of the manufacture web sites, you see how they are better than the others. What I have found most of the items they put into there RV's come from only a few suppliers. Most have plastic sinks, the same little drop lights, most of the stuff are the same. If they are selling so many of these items the price drops. They should make a better RV. the reason I am saying RV, to cover from a Class A all the way down to a pop up. I know the high dollar RV's are different. They are made one of a kind or better quality. I think they could do better how I am not sure. If I were to go buy a new trailer and I could spend a couple of thousand dollars more and get a better made RV. I would be willing to do so. Think about this eighteen wheeler go down the highway. The have fiberglass walls, roof that don't leak and they are not that expensive for what you getting. I just think they could do a better job. Thanks for all your in puts.
