Towing Capacity?

I have a 1988 Chevy Cheyenne 3/4 ton pickup, 5.7 litre engine, automatic transmission with overdrive. I'm towing a 7x14 enclosed trailer, approximate gross trailer weight when the water tank is full is 5500 lbs.

This past week is the first time I've had to haul water to a jobsite, and it was a for a 4 day job...many trips to the local utility reclaimed water depot. I've noticed several times that when I'm towing the trailer with a full tank (225 gallons) I get a brief stutter when shifting from 1st to 2nd (automatic).

What I'm trying to find out is what the towing capacity is for this vehicle...Anyone have any ideas where to find this? I'm seriously considering changing my tank with a 500 gallon tank that I have...but that will add another 2200lbs to the trailer. The trailer is rated for it, but can the truck handle towing it?

I've seen some of you guys talk about having a 250 gallon tank and how that's just plenty...I don't see how unless your jobs are only 45 minutes of actual washing each and you fill up between jobs, or unless you're running 2GPM. I suck that tank dry in about 45 or 50 minutes of fairly steady washing. For a job that took 28 hours total, about 10 hours of that was time spent driving to and from the water depot.

I will also be checking into whether or not our area offers hydrant meter rentals...that would have saved me a lot of time, and them a bit of money.

the truck should pull just fine ! check your u-joints and make sure you have good brakes!

U-joints are fine, brakes are good, and of course, the brake actuator for the trailer brakes works just fine!

Thanks for the tips, though!

It could be a couple of things...

-if your water tank is not baffled then it could be the water shifting about until it catches up with the truck

-the other could be something called driveline lash where all of the components may be within specification but the combined wear allows for some additional movement until everything is evenly loaded

Hope this helps? Cheers.

Oneness,
Check the drivers side door where the locking mechanism is.

Usually the info you need will be on mfg. tags there.

Are you towing in OD? Might try D in town and switch to OD once highway speeds are acheived.

Actually, never towing in OD. With this truck, you're not supposed to run in OD when towing at all. Checked the tag, no info regarding towing capacity there. Thanks though!
