Motors do not like sitting around and you are not driving enough to really exercise and engine without long periods of standing which is horrible for the engine. By the time the kids are bigger and out of the house or big enough to care for themselves, you will be ready for a new rig so go with BIG suv with the long wheelbase and able to pull the trailer and then when kids fly the coop, get a class A and be done with it. Class A will depreciate by as much as 50% in 2 years, scary but true!! NOT all but some and that is like urinating money away! Trailers depreciate less and cost a lot less to buy, insure and maintain.
