Etiquette on contacting past owner of your new RV

I wouldn't mind it at all and I would go as far as to I would encourge it. Before I got my new 5er I was looking at a used camper, but the roof had a strange coating on it and was wondering what the coating was with us being new to camper and such. I know people coat their roofs and I was just going to ask if was routine or if there had been a leak. The dealer said he would get us their number and never did, so we walked away from that camper.
