I recently acquired a TT with a bit of floor rot. Cut out all the vinyl flooring, fixed water issues, new floor joists, insulation and subfloor. When it came time for a floor covering I chose laminate. I do a good amount of home improvement work and am comfortable with it. Came out great and I'm happy with it, here are some tips:
Check your clearances throughout, doors, cabinets and wherever the laminate will meet with other flooring, like bedroom carpet. Keep the floor's thickness to a minimum, you're better off going with something less than 10mm. Homes are more forgiving with the space (gaps) needed for expansion and contraction but an rv is way more susceptible to those temperature changes so make sure you leave a proper gap...all the way around. You can use a colored caulk to finish the edges of if you're not happy with the way that will look, install 1/4 round for a nice finished look. (Provided you have clearance and can make nice looking returns. Almost all laminate flooring today are the type that locks into each other so you shouldn't worry about it coming apart, just make sure you don't buy the cheapest floor available, I find that the locking tongue and grooves on crappy floors are a problem. This is important...even though the floor will lock together, run a bead of glue on every board that is near a water source. The entire bathroom and the area near the kitchen. This is true for all laminate flooring applications, whenever you install it near water, glue it. This way, when water gets to the floor, and it will, there is less of a chance of it seeping into the groves, getting under the laminate and breaking down the floor from underneath.
New to the site btw, so if I figure out how to post pics, or if we can, I'll share.
