I have had a 27’ and a 35’ motorhome. The 27 was fun and fairly easy to maneuver and park. The 35 sucked at everything except when you finally got to where you were going. The 27 got 10mpg the 35 6mpg. If you tow a car, unless it is on a trailer you can not back up. I’ve had tow bars and tow dollies these can’t be backed up. That is a real issue because in the back of your mind think every time you start down a narrow road you’re saying to yourself can I ever turn this thing around. When towing you must find a place to pull through every place you go, every parking lot, you name it. And you are longer than some semi’s. The motorhomes are nice with older or more kids and long trips but after that a lot of downsides.

I think with one small child or a baby I would go 5th wheel. Almost any time your wife needs a break you will too. You need to keep babies strapped in any time you are moving anyway. You can jackknife a 5th wheel and turn it around in tighter places. You always have a vehicle to drive when you get there as well. Personally, I would look for a 5th wheel with the lower height overhead bedroom area. With two people and a baby you don’t need a stand up bedroom that reduces your mpg when towing. The smaller the trailer the smaller the truck you need as well. Standard single tire axles so you’re not wearing out six tires on a dually.

I have more info but don’t want to drone on.
