Towing Issues: Towing enclosed car hauler, champ car race, air suspension kit

Question
I have a 1987 GMC 2500 Van, that I use to tow my race car on a flat trailer. I have installed an air suspension kit on the rear axle to keep the rear end up. We need to tow an enclosed trailer with the car this ummer to a Champ Car race where we are in a support race. Will the van be up to it?

I am lookiing at about a 20 foot trailer, and the car weighs about 2100 pounds.

Thanks.....

Answer
I would love to give you an answer for this question..  BUT not gonna happen..

You need to find the towing capacity of the GMC van, and that is just the first thing to work on..

You have to consider the weight of the trailer, the car, all the support equipment, the people in the van....

All of these need to be considered as homework to establish if you can do this...

So the answer I have to give you is  NO IDEA if it can do it...
