At 1300lbs I don't think I would want to tow daily, but if you do it every now and again you shouldn't have too much trouble.

I agree that adding a tranny cooler would be a good investment.

If you have the ELC system, I think that will give you all sorts of fits every time you hit a bump and the trailers receivers transfers the weight and the ECL commands to pump the shocks up. If you have the ELC, I would wire in a disconnect switch and shut it down after they pump up to level the car after the trailer is connected.

The biggest problem will be to find a hitch and receiver that will work on your car and still give you ground clearance.

I don't think he has ELC, but even if he did, the system has timers on it, I think they are in the neighborhood of 15 seconds.

Good info on having the ELC or not.

The only timer I can find is the exhaust solenoid on the system. It will set a DTC if open for more than 10 seconds (based on my 2000 FSM).

I'm still digging though.....

My dad has an Avalanche, and since owning it new he has hated it. In the shop alot and his only gets about 15-16 MPG avg. He got rid of an old F150 and actually misses it I think. Thing was bulletproof

Must have got a fluke build. Mine was bullet proof and the only time I had got crappy mileage was when I was towing my buddies pontoon boat. I loved that truck.

I could actually go from Crestview, FL to West Memphis, Arkansas on a single tank.
