We went from a 27' Winnie to a 40' Tourmaster. I took it for a test drive around Houston. After 4 hours, I was an "expert". You will be too...as far as size goes, we found the 40' was too small after a few months of full timing. Others will disagree, of course...we have some acquaintances that full time in a truck camper and love it. We simply like the amenities our coach has to offer. We prefer the luxury over simplicity. That's what makes RVing so great. Go with what makes you feel the best....a 27' coach can certainly go more places than my 45', so points for you. I can take a 45 minute shower without losing any hot water, so points for me...decide what's best for you and go for it. It may seem huge now, but with a few hours of seat time, it'll simply be a big van....:B....Dennis
