You mentioned not wanting 2 drive trains but the advantage is when 1 breaks down you still have mobility with the other one. DW & I started in 1969 with a 21' TT and a '69 Lincoln as the tow vehicle. Now days it takes a SUV or truck to tow a TT that weighs 4000#. We had everything but a truck camper and I am now on my 5th MH. I have a 38' Mountain Aire that is very difficult for me to get up the 6 steps and I just bought a 19' Roadtrek that goes anyplace. There is a huge comfort difference from a luxury Class A to a small Class B but it is what I can get into alone now that DW passed away. I have taken 1 trip and another planned in 2 weeks using the little one. Any RV can be very enjoyable.
