i am helping a friend paint his motorhome in his driveway, so it can be done. we have been doing it a side at a time and at this point only have the front painted(but that looks as good as new). taking off the old stickers was the toughest part. they were old faided and cracked so the eraser wheel was the best for us but very time consuming. assuming you have tools i think the 4-5 thousand dollar estimate is way high. we will use about 4 erasers, tape(we use newspaper over the windows so not including that in cost), sand paper,primer, thinner and paint(a gallon did the front-so figure 6 for the whole motorhome). now the bad news we started last year but since we are outdoors there were more days we couldn't work on the motorhome and we used it all summer. my advice is if it looks like my friends, even with just the stripes off and sanded it looks better and after painting the front(and we are not even close to professionals) it looked great. go for it, just be patient and don't expect quick results. take pix and post
