In all my reading at both sites, Minnow seems to be a glaring exception and just another confirmation of that old saw "Feces Occurs." . We picked the 22 primarily because of it's size and the storage problem here. When the Jenny B is in it's land berth, even with the folding trailer tongue I only have about a foot rear clearance. Public storage - especially secure storage, is very expensive and current marina fees are $10/ft. and up here in $unny $an Diego.
To be honest and coming from an RV background as well, we really caught the 22 fever after reading the adventures of one couple who are living their dream pretty much full time.
One mistake many novice RV'ers make is getting seduced by the amenities of a larger unit. We've always lived "out of" our RV's, not "in" them, so for us, smaller is better and we're finally immune to "twofootitis". (the burning desire for just another couple of feet.) Over the years we've had RV's between 16 and 32 ft. and are very satisfied with our present 26 footer. It's a "Go anywhere" length with no towing/parking/space available concerns. Eventually we're considering downsizing again.
As far as boats, coincidentally we've also stayed between 16 and 32 ft., and if (or maybe when) we go to a boat show and factory tour, where Dory threefootitis runs rampant we might change our mind too and move up, but 'till then the 22 fits our personal needs 100% of the time and our personal desires 87% of the time. I already have a more than adequate tow vehicle so it's not an issue. Probably the biggest reasons not to move up are age/fitness issues related to single handed launching and recovery and losing the ability to easily "go anywhere anytime". We still have that same dream Bill and El are following, and I'm not yet ready to give it up.
