The 4 seat buggy idea is a bit of a hard deal, as it is I had both kids wanting to go with me this year at BB, and as they are both getting more interested in out door stuff I don't want to hamper that at all. My wife really doesn't care to partake in my shenanigans and worries that I'll corrupt and hurt the kids. I don't foresee either of my kids being sports types, my daughter may do sports later but as of 1st grade she has no interest in things other than horses, horse showing and doing things with me. Hell she helped me trim out a new exterior door yesterday just to do something with me since I don't hang out inside the house much.
I look at the different vehicles like this, the Crew cab might entice my wife to join in some easy scenic trails local to my house, and it gives me a truck to do truck things when she takes my diesel truck to horse shows. The 4 seat buggy idea allows the 1 time a year the whole family goes wheeling and otherwise lets me either invite a friend to come along with my kid or kids or they can have a friend or friends along. A new 4 seater will probably be lighter and more capable than what I have right now too. In some number of years from now (daughter is only 7) I can always go back to a two seater if that makes more sense.
