i vote suburban or excursion. goes diesel in the excursion. pulling a trailer wont always be practical. you have to think that with the seating required, there needs to be gear room to. an excursion has close to 4 feet of space behind the third row seat. burb is close to that too.
if you must stick to the smaller mid size, a 94-96 mitsubishi montero SR will give you 3 rows, good for 7 passengers. all 3 rows are reclinable. an sr has a big sunroof, rear locker, 3 way adjustable shock system, and easy to clean leather. 215 hp 3.5 v6, awd selectable transfer case. there is a guy in cali running 37's on a 3" body lift with some trimming, and wheels in the rubicon. has not broken a shaft yet. he is a friend of offroader, here on the mitsu board. offroader is running a 2" body lift and 35's. i have all stock with 33's. i get 14-16 mpg loaded for camping with the a/c on. 15 unloaded flat towing my samurai in the rocky mountains.
awesome platform, and significantly cheaper than a 80 series. half the price or better than a 100 series.
good luck with your choice.
