The VERY first thing to remember when and if you get a motorhome, look up! Overhead clearance is something you don't worry about with a Honda Pilot but a class B or C will be a lot taller. My B is 9'2 tall although I have 9'6 over the windshield in case a mechanic or someone else drives it. I don't want to get it back 6 inches shorter.
I love my B but it's just me. My new ladyfriend wants to travel a bit and we should be okay but it'll be cramped. Then again, I'm 6 foot and she's 5'11. If she likes it, I may end up getting a C or at least a B+. The advantage to the B is I can use it like an oversized conversion van. Another advantage of a B or C over a trailer is breaking camp. I watched a neighbor at the last RV part breaking camp. Raising jacks, hooking up and so on took about 30 minutes. The same when they came in. Once I backed in, it took me 5 muinutes to hook up my electric and about that when I got ready to leave.
Now, you have two little ones. Whatever you get, make certain it has at least two captains chairs that can hold child seats. Mom and dad can sit up front and the little ones can be safe in back.
If I might make a suggestion, why not invest on a Conversion Van? You can get one with a raised roof. Most are based on 3/4 ton vans but I've seen minivans such as Astro Vans converted. Then you can pull a small camping trailer or even a small enclosed cargo trailer with tents and camping supplies. If you like camping and the kids take to it too, then you can lay some money for a dedicated motorhome. If it's too much trouble, sell the trailer and you still have a nice spare car to hold the kids and their sports equipment as they get older and bigger. Another bonus is when you're on a trip and a diaper needs changing. Mom or dad can stand up and change the diaper out of the weather. One last advantage to a conversion van is if heavy rain rolls in, everybody cvan get under a hard roof in the van.
