Additional ancilaries?

Anyone have an on-board air system in their truck?

It'd be nice to have for airing up tires or using an impact wrench.

I'm not talking about a little 12 volt cigarette lighter plug type air compressor, but something with some CFM...

I was thinking engine powered.

Also wondering about a 120 volt generator driven off the engine.

We added an air cooled two cylinder compressor to a 6.9 years ago. It only fit because the truck didn't have A/C. I should've got a pic of it. Funny thing was it was for a high school kid's truck, he wanted to run an air horn!

Maybe I could remove the vacuum pump and use the suction side of the compressor to provide vacuum for the brakes and HVAC system.

I saw one about 25 years ago, it was on one of those tire service trucks that came to our farm to fix a tire. I had a aftermarket head bolted to one side of a V8 gasser that when needed converted engine compression to a compressed air tank for air tools and airing tires. I dont remember who made it and I havent seen one since but at the time I though it was pretty neat.

i saw a ford years ago that had a 120 volt alternator running off the engine. it looked like a giant old "chrysler style". if i remember correctly the truck was some type of service truck that had a lot a power equipment in the back. also made a "whirling sound" when running.

Actually since under hood space is rather limited, you could consider a PTO driven unit.
A lot of the service trucks these days are using hydraulicly driven air compressors.

There are also boxes that can get 120 volt AC current out of an alternator.

I would also think you could run on off hydraulic motors driven by the same pump that runs the air compressor if you wanted to.

I have seen belt driven air compressors under the hood.
I have seen belt driven generators mounted under the hood.
But I have never seen both on one truck.

Belt driven air compressor would be the priority. As far as the generator goes, I'll upgrade the alternator and run an inverter if there's no more room.

Ihave seen belt driven compressors on some older heavy equipment that seems would work easily for you. i would want to use an elec. controlled clutch to turn on/off as needed as compressors draw alot of power

I'm probably gonna take a cue from the offroading guys and get a "york" type compressor from a Volvo. (It has a seperate oil resivour, rather than relying on the freon for lubrication.)

I'm looking for a place to bolt it to the block.

Your car hauler is a roll back isn't it?
You already have a pump and PTO.
All you would need is another valve and hydraulic motor.

Here is a belt driven unit that fits on a CAT engine.

No pump, No PTO... There's a place to bolt a PTO, but it's not there.

The bed is fixed, I slide ramps out from under the bed to get cars up on the bed.

engine mounted compressor for air

look at some older model medium size trucks or buses that have 6.9s or 7.3s with air brakes, most have a storage tank also. good luck

The truck or bus air compressor would not give you enough CFM to run an impact wrench for more than a short burst unless you had rather large air storage tanks.
It would give you on board air for tires and such though.

I saw a program about Jeepers playing in the woods and one guy had an underhood arc welder set up. Undoubtedly you could pull AC off of that as well.

An older off roader trick was to use the York compressor to supply the air, then had their tube bumpers work as air tanks... Yorks also came on the older Fords and Dodges. Some of the Dodges had 2 cylinder compressors.
