Well, here is my current line of thinking.
I currently commute 49 miles each way to work.
I drive a Saab 93 which gets about 31mpg (98% highway miles). Towing capabilities non-existent.
My wife drives a Nissan Quest minivan which does have the tow package. However, towing capabilities are small (popup) due to limited tongue weight.
She needs the space to transport kids and for her work which requires her to transport a few totes around.
It doesn't make sense for me to get a truck that can handle towing a camper or 5th wheel. So I'm thinking Class C or Class A. Maybe Class C as as they appear to be more affordable and especially if they have the bed over the cab, however, I've always loved the Class A's - and I could also tow one of our cars along for the ride too.
I'd most definitely look for a used one that wouldn't be much of a burden on payments if I finance.
Storage shouldn't be an issue either. So that's where I'm 'leaning'....
We've always done 'camping' in our tents locally and we've always had a great time. It's funny - as it stands now, my kids, my wife and I LOVE the adventure of 'getting there'. We love the road trips. Kids are 5.5 and 3 right now with another one on the way in November....I haven't figured how a baby would be transported in one of these yet...
sorry for the long response!
