Bought a 08 3300sk about 4 weeks ago and while at the dealers lot I noticed that the slides when closed have a wider gap at the bottom than at the top the dealer said it is normal, is this right ? Everyone that looks at my camper comments about why the closed gap is wider at the bottom. If it needs adjusted, how is it done I'm very mechanically inclined if someone would tell me what if anything needs done I would do it myself. Hate to take it back to dealer that told me it was normal and 125 miles away.
