*Is the plan one trip across country with the menagerie? Or will you take them each summer when you travel?
If it's a one time trip, I wouldn't let the animals drive the RV choice.
There's a reason kids are mandated to be belted in...applies similarly to animals. Each should be in a small secure cage while traveling.
A full size van pulling a trailer would be a good option as there is plenty of space for pet crates but even a 4 door pickup could easily be outfitted.
When looking at small motorhomes, consider where you could put those crates without it being a big hassle moving around them all the time....of course with that many animals, it's always going to be a hassle regardless of RV type.
