john's pretty much spot on. they can be hard to justify for only a few trips a year. if you already have a pickup that can pull a travel trailer, would be a better way to go than buying a class a, since you can disconnect and have something to drive around, unless you plan to buy a sub-compact maybe for the class a to tow. if you're retired and really want to do heavy traveling, i'd probably buy the class a and tow the vehicle, but for the 'every once in a while family', i'd buy a family-style travel trailer and tow it..fewer maintenance issues/not as complex. the more you use it though, the better you get at packing and knowing what to bring, etc.
