Hey, just another forum newbie. Just purchased a 2004 Dutchman Aerolite Cub model 160. Love everything about it but the floor needs replacing. Yeah I know....BIG, BIG job. I've spent days watching Youtube videos on replacing floors in RVs, but nobody talks about what in the heck you do under the bathroom, kitchen sink, & refrigerator. They all discuss removing the cabinets, but you're looking at plumbing too. I've also read that some people have approached this by going in from underneath the trailer and adding studs from that angle, which to me seems like the way to go, and once studs are in where needed, then pull up the floor only where needed and screw in to new studs. This seems like a way to do it without removing the entire interior of the trailer. My question is, can it be done from underneath, and how do you then replace the metal or rubber seal again?
