You are fine with an RV built and maintained to factory specs. For sometime now the majority of tractor trailers are 102" wide. This dimension is for the body, not including lights, latches, awnings, mirrors, etc. Most older RVs were 96" wide (my 1997 Itasca Suncruiser was) but today just about every big truck and RV are spec'd to 102". Have fun and take it easy on narrow two lane roads with your new Coachman.
Sidenote: In 1987 I was truckin' on a two lane road in Massachusetts with a 102 wide semi trailer. Going through a small town the local cop pulled me over. He had a tape measure and he ticketed me for being off the "National Network" with a 102 wide. Then and now I have no idea [moderator edit] the National Network is. I do know that little town had a balanced budget that my employer contributed to.
