Also I imagine the bigger the unit the more money it is going to cost you to go anywhere along with all the headaches of the road traffic pulling the whole house along with you....
We are in our mid 70's and it sure is nice to get in our 2010 F150 truck and tow our 4200lb OFF-ROAD POPUP trailer from Northern Neck VA to Gatlinburg TN (458miles) on one tank of gas... No wind drag to deal with at all...
Not much overhead money wise for the small units...
About the only expenses we have is maybe a new set of two tires ever so often and Insurance and Inspection Fees etc...
Yes we lose out with lots of open space inside the small trailer but we still enjoy ourselves... Makes us enjoy the outside more haha... We started out in the 60s being avid tent campers...
This is NOT a full time thing for us I guess as we still maintain our regular house in Virginia...
