Hi Paul & Ann
Thanks for the links, the hard part is finding an A class under 7.5 tons.
Just looked at your travel page, we have been to some of the places you have mentioned Flagstaff cinder cones volcanoes, Grand Canyon, had the flight in the helicopter from the same airport just outside GC, had a great steak from town just outside the rim.
If you know any models of RV under 7.5 tons it would be a great help, we are planning on retiring early and buying one over in the USA, staying for 6 months, then returning home, as this will avoid paying taxes on importation.
Regards
