RV's are great! We bought our Class-C a few years back and have been traveling and flying it up everywhere. A utility trailer to tow is the only way to go, you can carry many planes and toys without hassling putting them inside your rig. Our rig is only a 31' so we can still get most everywhere we want with no problem. I''m into my second year IMAC at this point, and just lovin life.
Don't wait 25yrs!! Just do it. I only wish I would have done it 25yrs ago, because there's things I would have liked to do then that I can't do now.. it's still a blast though.
