Boats are expensive to keep, we have several boats in couple of locations around the world and its expensive to keep them there and if it were only for private use i wouldn't bother, but we charter them so it's fine for us :-) and if we want to go back to water we just fly to where we want to go to.
For us this is to be complete change from what we were during past 10 years. In my head i compare MH's to the power boats and trailers to sailing ones (or cats) :-). i know its completely wrong comparison but thats how i think of it.
We want to take it easy, as i prepared the rough trip plan on roadtrippers.com i plan max of 200 - 300 miles crossings and then spending time at the places we get to, to really enjoy the locale, be it coat, mountains, lakes, woods, cities etc. we will not be in rush and even if we require to break, we would just camp on some campground and then catch the flight to wherever we want to be.
There is another question SRW or DRW ?
Also missus just brought up a question i have no answer for, why 5er and not MH :-).
