I have to agree there is no one right answer. I wouldn't stress about
it though. We've been RVing ALL OVER Europe in a 1998 Ford Rimor for
the last 4 years and bought it on a quick whim. We've had no problems
with it and have found it to be the perfect super cheap home/vehicle/
storage unit to keep in Europe ( super easy now that we know all the
best sites).
We also did lots of traveling to Mexico, Baja & USA in an old Datsun
minitruck with a 6 pack on top that we bought on a whim. Again no
problems ( over 250,000 miles on it). ( This might be the best of both
worlds as one can use the truck for long stays while leaving camper in
camp).
There are pros and cons to the RV or Caravan and car models and it's
personal taste. The good thing about an RV in Europe is you park and
are done. The Caravan deal looks like a LOT more work to settle in.
Also I've had friends that have worried about being robbed in a
caravan and felt they would be safer in an RV where they could quickly
take off if needed. Much depends on how you will travel ( long stays
or moving more?) and what the mass transit is like. ( Wonderful in
Europe where a car and parking is often a bigger hassle than it's
worth.). But I think I could handle any of the above without
complaint.
I would have something where you do not have to make up a bed. That
gets old REALLY quick.
Surprisingly one adapts VERY easily to a small space if everything you
need is easily accessible. That was my biggest worry as we had lived
in a very large home, but we live for 6m out of the year in a VERY
small RV ( van sized with cab over for 3 people) and adapted easily
and immediately.
Neither of ours was our first choice in RV, but they both worked out
well without any planning really. Trust your gut.
Another key is to follow the weather. Cold, rainy weather is not fun
in a small vehicle home IMHO. No problem for a few days, but being
able to add the grand outdoors and perfect weather makes it all so
much better. Having the beach or trees or beautiful lake etc as your
living room ( ie lounge chairs, table etc) is part of the bliss.
Ease counts a LOT and good vehicle that it is easy to fix.
By the way, we will be doing a USA road trip in the fall of 2011
( after Asia ...where we are now...India and then Europe for the
summer). Maybe we'll run into you. ;)
Good luck!
