Looking at new tow vehicle

[nipper]

Just got off the phone with my mechanic and my wife's 1998 chevy Suburban 4WD needs another $1000 of repairs. I love that truck, but lately, it has been killing us on repair costs. I really do not want to break down and buy a new tow vehicle, but at the rate the repair costs are draining us, I am considering purchasing a new tow vehicle. I have always purchased used vehicles, but I am considering a brand new one given some of the deals out there.

So, any recommendations on tow vehicle would be greatly appreciated. If possible, I would like to have a 7 seater, which limits us to not that many vehicles.

Any comments on your towing experiences would be appreciated. Thanks.
