- The SR has tranny and oil coolers.
- The 5000# capacity is for pulling a trailer with brakes. Otherwise I believe they say 1500#.
- As for air bags, can't say myself from experience. But I had well over the 1000# cargo rating in my 95 SR in the form of bricks (proly a good 1200#). You could certainly feel the weight, and it was sitting a little bit low. The rear wheel wells were below the front. (Looked kinda like a 4Runner!). You're looking at 400# in tongue, plus interior cargo. I would think you'd be well under the 1000# unless you have abunch of poeple in there with you.
