We had a 2008 Raptor 3712TS (40') from which we removed the decals. Watch YouTube videos - we basically used "rubber eraser wheels" to rub them off. Then a chemical cleaner to remove the left over adhesive. It took 2 of us several WEEKS to do this - talk about a lot of work!
That left us with a white trailer that now had shiny white paint where the decals had been surrounded by oxidized white paint where there were no decals.

So I had to buy a very expensive Cyclo dual-head buffer and buffed the trailer with rubbing compound followed by two coats of sealer/wax. This took addional WEEKS to accomplish...but it looked great!
Problem was, within about 6 months it was back to looking like the second photo. So we re-did the rubbing compound and wax. Turns out, this needed to be done at least once per year, and more often if you didn't want the prior decal areas to keep showing.
There probably are better waxing/protection products available now - but the same amount of elbow grease will be needed to remove the decals.
For us, our conclusion was that we would NEVER do this again. I would trade a trailer in on a new one before I ever attempt to remove the decals. Yes, it can be done - but plan on a project that will consume your life for a matter of weeks! At 72, I'm also not a big fan of working days on end from high on a ladder. One slip could change your life, so count the cost!...JMHO
