1999 chevy suburban

Sounds like you could be overweight, unless the Suburban is a 2500 model and not the standard 1500 model. Also, a vehicle with 190K miles and 15 years old may be problematic, depending on condition. I have a 2012 Avalanche, which is basically a Suburban with the back end modified into a truck bed. It has the standard 5.3L engine. I was worried about towing my new 2014 Bullet, which is 28' long, one slide and is 5200 lbs dry weight. However, it seems to work pretty well so far in the two trips I've taken. But yours would be significantly heavier being 32' long and two slides. I would not want to tow anything heavier than mine. Also depends on how many people and other cargo will be in the Suburban....

The age and mileswould concern me. Otherlwiseyou should be O;k.

Depends on the TT weight, which could vary significantly from model to model and brand to brand.

Only if 3/4 ton Burb with 7.4L.

I'm going to assume that its a 1500 Suburban with the 5.7L engine with 2WD.

A quick look at the towing guide (http://www.trailerlife.com/wp-content/uploads/2012/01/Trailer-Life-Towing-Guide-1999.pdf) reveals you can tow 6500 lbs. You need to have the upgraded transmission cooler & radiator.

If you have 4WD, you can tow less.

As Doug33 mentioned above, on the half-ton Suburbans, one typically runs out of payload before exceeding the tow rating.

If you happen to get a 2500 (3/4 ton) Suburban, the field opens a bit. From there, you would need to know:

Which engine does it have? 5.7, 6.5 diesel, 7.4?
Which rear end gear does it have? 3.73 or 4.10?

Most common are the 5.7 and the 7.4. 4WD tow rating is lower than listed:

5.7L Engine:
3.73 gears - 6000 lbs
4.10 gears - 7500 lbs

6.5 Diesel:
3.73 gears - 8000 lbs
4.10 gears - 8000 lbs

7.4L Engine:
3.73 gears - 8500 lbs
4.10 gears - 10000 lbs

^^^^ What he said. A 32' anything with 2 slides will be far too heavy for a half ton Burb.

I had a 1/2 ton Suburban of the same vintage as the OP wants to buy.
If the OP is indeed looking at a 1/2 ton Sub, no way is he going to be happy towing a 32' trailer. With 190K miles, if the auto trans has not been replaced/rebuilt yet, it will be soon after towing that trailer.

If its a 3/4 ton with the 7.4L engine, then it will work fine, although the maintenance done on the trans in the past will determine its life. The 3/4 ton trans is a 4L80E, which is stronger than the 4L60E in the 1/2 ton.

BTW, I now own a 2002 3/4 ton Suburban with the 8.1L engine and tow a TT that is 31' and has 2 slides.

My 1999 Chevy 1500 Suburban is rated for 5000lbs max according to the owners manual. It did not have a tow package installed or a different gear ratio from the factory. We did tow our Jayco 27BH with it for 2 years. Once we wanted a larger TT ( 35' with 2 slides) we bought an Excursion.
