Thinking on towing a Malibu m235 dry weight 6200# plus trailer 1700# with a 17 suburban z71 4x4 5.3L 3.42 gears (rated towing is 8000#).

1. Anyone towing 8000#s with their suburban?

2. Anyone added bags to a 15 16 or 17 suburban?

Thanks!

Need some details on your Sub. Which version? Z71, LT, LTZ? It might have some funkiness if you add airbags to one of the LTZ with mag ride suspension. Z71 should be fine to add airbags to. As for the max towing capacity, how far are you going with the boat? The Sub should be able to handle that--if it is just the boat and trailer. Once you add passengers and cargo plus the boat (and fuel and gear), you are likely to be overloaded.

I think he said it was z71.. and I agree that a short distance should be fine. I have a buddy that tows a 32 footer 5 miles to the boat ramp with his Colorado regularly with no problems. Keep it out of OD for sure.

One additional thing to consider: Terrain.

I live in a pretty hilly area. Wouldn't want to be overloaded and having to climb and go down many hills, or stop in a panic. On the other hand, my brother lives in a very flat area, which is a totally different situation for towing.

One thing to think about though. In a boat, there is a BIG difference between 'Dry' and 'Wet' weight. Fuel alone can add up quickly. Then you need to factor in anchors, coolers and all of your equipment too. I was shocked many years ago when I decided to actually weigh my boat. Wet, it was alot heavier than spec'd. Imho, you can be pushing 8,500 or more pretty easily. So, knowing you are very much at the upper limit, it really depends on the distance, the grade of the terrain, etc.

stopping it will be a bigger issue than towing.. once rolling you should "fine" i mean its not going to tow like a diesel but the parts of the truck should be fine.

ive towed a 1994 26 foot crown line with the 454 in it, not sure the weight of boat and trailer but it did fine with a 15 denali.
