Some considerations
A motor home is very fast to set up compared to a Trailer, even a solid trailer.
IN fact if I parked in the rain I could do all the initial set up without setting foot outside the rig on my class A. Run off batteies till the rain let up enough to plug in.. also when traveling (in the rain) and feel the need for a rest stop.. Every thing needed was IN HOUSE so no need to get wet.
Finally in this line. Most motor homes have generators. I put one heavy duty outlet on the RV and used it to power the house when Detroit Edison failed. Worked very well very very well. I only needed about 3500 of my 5500 watts (120 volt only no 240 volt stuff).
Another consideration MPG.. No matter if towing a Nice Trailer with a bit Pickup or towing a small car with a similar size class a. About the same MPG.
But running to the store for a loaf of bread... Car cn hit 25-35 MPG. That big pickup, if you are lucky 16-20
Finally.. a word of advice.. As you travel the water is a bit different, it can take you a few days to adjust to the differences in the bacteria and mineral content of the local water... During that time there are often what I call.. "After Effects"
And the length of "Just a minute" depends entirely on which side of the door you are on.
So a bath and a half Class A.... 2 holes... No waiting.
