I've had many over the course of the last 20 + yrs....
* Get as new a one as u can afford... they tend to get better gas milage.
*Bigger is NOT better
*Get big enough for the 2 of ur to be chummy but not falling over each other.. remember there will be days of inclimate weather
*Class A & C have more storage
*Trailer have more livablility.
*5th Wheels are more stablile.
*get an awning if u can afford one, they are so nice in teh sun at the end of a long day driving
sit back and enjoy
