best way to remover stickers from a 2011 tiffin open road

A high strength CITRUS cleaner-degreaser with plastic wrap over it on the decals. Let sit for an hour and then a plastic razor blade to peal off…5X better than Goo Be Gone.

All adhesives are made with oil. So baby oil or any very light oil will loosen up that sticker.

Each year I remove some of my decals as they shrink and peel. I just park the camper in the sun and they literally scrape right of as they warm up. Sometimes I use steel or plastic razor blades to help them along. All residual glue comes off with the Goo Gone.
Once off, I tape the old outline, scuff the surface with scotch brite pad. Clean with thinner and then spray paint. Has been coming out great. Just needs to be calm day with low humidity.

I don't know if you're talking about factory or owner applied decals/stickers. While the methods to remove them can vary, I have found the best way of removing the adhesive is with a Rubber Eraser Wheel

I've had good results with a hair dryer, plastic/nylon scraper and WD 40.
I've also had good results with the gel form of Goo Be Gone.

Stickers are on the coach. Thanks for your comments

By 'sticker' do you mean bumper stickers, or graphics?

Either way, use a heat gun (or a good high-wattage hair dryer). Work a few inches at a time -- heat it and peel it, heat it and peel it. Any sticky residue remaining can be removed with WD-40. You'll undoubtedly have some 'ghosting' where the stickers were, which could require some professional buffing, or at worse just leave it alone. Depends how long they've been on.

Trade it?

Sorry - not helpful.

A LITTLE heat and a plastic razor blade is what I used on my parents Tiffin. It's a tedious job.
