Just to clarify one point. The axle capacity on the rear end, is that the hitch weight, so for instance a 6000lb trailer at average of 10% = 600 lbs so being well within capacity, or am I missing it again?
With a properly rigged weight-distributing hitch, there will be, roughly, a pound-for-pound addition of weight from the tongue to the rear axle. Typically tongue loads run 10-15% of trailer weight. So, you have 1113 pounds of unused rear axle capacity. With a 7500 pound trailer, you would expect to have between 750 and 1075 pounds of tongue weight. If you get a trailer that large, you'll have to be a little sensitive to rear axle loading and maybe make a few trips to the scales until you're sure but it will still work.

Quote:
And you are right, I am not interested in what I CAN tow, I want to ensure that what I tow is safe spec wise and within my comfort level. I am still looking for a trailer and have several criteria for choosing. I am not inclined to change this vehicle just yet and feel that I will be buying a trailer that is within its capacity to tow anyway. I just want to ensure that is the case.
The thing to watch is that the specs can be misleading. In general towing ratings have increased each year for the last 15 years or so. It is unclear whether there is actually a commensurate change, mechanically, in the vehicles being sold in many of these cases. The ratings are themselves a sales tool to sell newer trucks and to push people into larger power train packages.

The other thing to consider, especially with an older van, is that you will have the trailer long after you sell the van. Accordingly, get the trailer you want, and then adjust your tow vehicle situation as necessary.

still pulling up links.
WikiAnswers - What is the towing capacity of a GMC Vandura 2500
it mentions the specs being on a sticker in the glove box. (you probably already know that ;-
)

The only sticker in the glove box has a bunch of numerical (looks like binary!) codes only, nothing to do with the specs, but I appreciate the suggestion

Are you sure that the van is really a 3/4 ton? With a 6600 gvwr, it sounds like a 1/2 ton. Every 3/4 ton van/pick-up in those years that I have seen had a gvwr rating in the 8400>8600 range, and would have had an axle ratio of either 3.73, or 4.10. The brakes, suspension, cooling etc.,are also bigger.

Welcome. Finally I get to help somebody. The folks on the Forum have certainly helped me a lot.

I have a 93 conversion van that sounds like it has the same specs as yours- 5.7L, 6600 gvrw, transmission cooler, 3.42 rear end, etc. I have a printout of the GM specs for my van. Not a whole lot more important info on it other than the trans is a 4L60E. I think the hp is only about 195.

I towed a large 31 ft Excella with my van. The weight was about 7500# loaded. This was between unacceptable and marginal. The van was way underpowered. I dealt with it the best way I knew how- shift manually, keep the revs up and go slow. The going slow also helped in another department- stopping. Now difficulty in stopping was not all the vans fault. Drum brakes just don't provide enough stopping power for a loaded 7500# trailer. Occasionally I would tow my 24 ft Argosy. This only weighed about 4500# and felt fine.

The numbers say you can tow more, but I would not tow anything more than 5000# with this vehicle.

rangebowdrie. I believe it is a 3/4 ton, I decoded the VIN and my auto Guy says it is as well/

TouringDan Interesting comment regarding the Excella, I am getting back to a seller about one tomorrow, a 31ft, so your reply is timely. I don't wantt o wast his time (or mine) and this gives me the answer I am looking for (for now) as regards this trailer. I also realise from another posting that this will not be my first or last TV but for now its what I have, with no intention to change it. The trailer will be bought with this in mind but also with short to medium term useage in mind as well. We have three growing kids and need enough room for them for now, but pretty soon they will not want to bother, so we don't want/need something too large either. The 31 ft was a possibility but I still prefer the idea of a 26 ft and one of the kids get to bunk in the van!

Bex the van should have eight lug nuts on each wheel if it is 3/4 ton. If it is 1/2 ton it will have five or six.

My old tv van, a 93 G20 Chevrolet, is supposidly a 3/4 ton model, but it only has 5 bolt wheel lugs. I have seen lots of G20 vans, but I don't think I have ever seen one with 8 bolt lugs. I always thought that my van was a 3/4 ton, but it never felt like a 3/4 ton. Also, the gvwr of 6600 lbs doesn't sound like a 3/4 ton. So I would say that maybe GM called this van a 3/4 ton, but in many respects (or all?) it is only a 1/2 ton vehicle.

Now I am really struggling.
5 bolt is what I have, so a 1/2 ton?
Many 1/2 tons (from what I have read) make better, or more efficient TV's than 3/4 tons, might this now be the case with mine?
Also, what the seller of this vehicle told me was the trans cooler is actually not. But I have one being fitted this week.
What about pros/cons of a brake controller and sway bars, both a must have? I am thinking yes for the sway bar set up and potentially for the brake controller, we do get high winds here, never stops being windy!
I realise this is probably for another thread and if someone wants to move it......
Its just easier, whilst there are good people looking here.

good people are all over :-)

if you use the google search you'll find lots to read. the brake controller is a must.

weight distribution and sway control are also needed for safety and comfortable towing.

You will then have to call the General Motors Customer Service people. They have to keep that information for litigation purposes.
You will have to press and when met with resistance just request to speak to their supervisor because you are not talking to the right person (take names).
It took me several weeks to get mine (1990 Rally S
TX G3500, 5.7L (350ci) window van, see my pictures) 12,500 lbs. By the way, my van has eight lug wheels. Its my understanding that the 3/4 ton should have 6 lug and the 1/2 5 lug wheels. If you have a 3/4 ton with 5 lug wheels then check the axle ratings, they will not be the heavest available for that year.
I tow a 1984 Excella 31 foot.
