Tow Truck
Can you still tow with a truck that has airbags?

You can definitely tow a trailer or your boat with an air suspension. In a lot of cases, you can achieve the same load-carrying capability as a stock truck or increase it depending on what size airbag you install and where you position it in relation to the rear axle. For bolt-on applications, we suggest checking out the kits from any of the suspension manufacturers advertising in Sport Truck.

4-6-8 Detonate
The current high gas prices are killing me. I don't know where they're going to stop, but I'm sick of it. I want to keep driving my '91 Chevy S-10, but even the 4.3L V-6 isn't exactly a gas miser. I thought about swapping in a 2.2L inline-four from a similar truck, but I'd still like to have a little more power.

I remember that a neighbor had an '81 Cadillac with a variable-displacement engine. I think it was called the V-8-6-4 or the other way around. Could that technology be adapted to my truck so that it could run as a six-cylinder when I need power and a four-cylinder when I'm cruising the highway?

Would I have to find one of those Cadillacs and take everything related to the system and modify it to fit my truck? Could I adapt the Cadillac system so that I could manually control the number of cylinders firing from the cab? What do you think?

We think that if you're smart enough to figure out all the technology necessary to make a variable-displacement system work on an older truck then you probably have some incredibly high-paying job, so gas prices don't bother you.

Can you remember the last time you saw one of those early-'80s V8-6-4 fuel-injection Cadillacs on the road? We can't, and we don't think you would have much luck finding an intact, working system from one. That engine was a dud. It was rough running and quite unpopular. We think that engine probably set GM back two decades on the variable-displacement concept. The present Displacement on Demand GM engines are very nice, but the same can't be said for those old Caddies.

Even if you could find a Cadillac with all of the components, you'd need to be an electronics genius to make it work. It was a very complex system that had many subsystems involving buffer amplifiers, computer command controls, vehicle speed sensors, ECM programs, etc.

Our suggestion is to keep your V-6 in top tune and drive as smoothly as possible to obtain the optimum mileage your truck is capable of delivering. Don't bother swapping in the 2.2L four-cylinder engine from another S-10 because that is quite possibly the lamest motor on earth. Leaky head gaskets, freeze plugs, and other maladies are quite common with that powerplant. Your 4.3L V-6 is a keeper.

Hi Mike,
I wrote you a letter two years ago that you published. In the letter, I apologized to you because as a police officer I was embarrassed that you were targeted by another member of law enforcement and it forced you to sell a project. Well, you told me to keep you updated on my truck. I went on to two-tone the truck and body-drop it. Currently, it's being completely shaved, and a cali combo has been installed. A 56-inch LED is my new brake light, and new paint will be sprayed this month. Thanks!

Your truck looks great, Darryl. I have only one question: Have any of your law enforcement brethren pulled you over for those illegal LED taillights yet? -Mike
