True. Perhaps if a WDH is not needed we can resist diving into another WDH discussion unnecessarily. Even if it is needed, linking to existing discussions should be sufficient.

Doesn't anybody have questions about the 2.93 axle ratibg for towing. Seems like that would be more of an MPG ratio.

You are right about the gearing as it is not ideal for towing but for a one ton glass egg he won't have a problem. We would also need to review what tranny is in the vehicle (gear ratios) and tire diameter. The op should not be putting on larger diameter tires as it would make the gearing problem worse.

It seems that way at first glance, but 2.93:1 is actually shorter gearing than the stock non-towing ratio for this year and model, which is 2.56:1.

Keep in mind that by today's standards this car has a large (5.7 L) slow-turning engine and small ( P225/75SR15 ) tires.

Thanks for all the posts. Since we are getting into the details, here's what I found on the door panel stickers and rear gate code specifications:

GAWR 5820
GAWR front 2554
GAWR rear 3266

4-speed4L60-Eautomatic (OD)
2.93 gears and limited-slip differential

Tires are 235/75 R15

Oh, and by the way, this OP is a "she". Motown car buff born and bred.

Thanks for the numbers!
That's GVWR = 5820, I assume.

The rear axle capacity is substantially greater than the front, which is appropriate for this type of vehicle and fortunate given how much load any weight on the hitch will add to the rear axle.

The total of the two axle capacities equals the GVWR, so the limit will be the rear axle capacity (or that and the front axle capacity if a WDH is used); this is unlike typical recent trucks which are having capacity issues, because their GVWR is the limiting factor (it is less than the sum of the axle ratings).

Guessing at a 60/40 empty weight distribution, the axle loads before adding people, cargo, and trailer would be about 2400-2600 pounds front and 1600-1800 pounds rear. About half the driver and front passenger weight, most of the rear passenger weight, and all of the rear cargo weight would pile on the rear axle, adding anything from one hundred to several hundred pounds more on the rear axle. A 300 pound trailer tongue would probably add another 450 pounds to the rear axle (and take 150 pounds off the front axle), so I can see getting up as high as 3000 pounds on the rear axle, but even that number is within the axle rating.

Personally, I would take the car to a scale, measure the hitch overhang (distance from ball to car's rear axle), list what I was going to carry, and work out a much more accurate estimate of rear axle load.

I think that reasonably configured trailers of the roughly 16-foot size class should be manageable without problems and without needing a WDH, although with that long rear overhang the trailer has lots of leverage to mess with the car, so some sort of sway control device might be helpful. A bit larger and especially front-heavy trailer could easily push the rear axle load over, and trigger the requirement for a WDH (or a weight-reduction plan )

Yes, Brian, you're right, of course. GVWR = 5820. I measured from the center of the wheel to the ball and it came in at 60 inches.

Again, thanks for real numbers to work with!
With a wheelbase of 115.9", an axle-to-ball overhang of 60" means that the overhang is 52% of the wheelbase, so for every pound carried on the hitch, 1.52 pounds will be added to the rear axle load, and 0.52 pounds will come off the front axle. With the typical tongue weight of a 5000 pound trailer, that would be a lot of load transfer.

This is about what I was expecting, so my example numbers don't change.

For comparison, a typical modern minivan has a little more wheelbase (120") and significantly less overhang, so they run about 40% instead of 52%. A "full-size" three-row SUV (in some ways the most direct modern equivalent) has the same 116" wheelbase and probably less overhang (e.g. Tahoe, Yukon), and the long versions (Suburban, Yukon XT) have much longer 130" wheelbase with similar-to-Roadmaster overhang... all of these are better off than the Roadmaster in ability to handle tongue weight. I think it's a good thing that a lightweight trailer in planned.

So true. Brian has the good info. The Roadmaster will work but the inherent physics of some mini vans make them a better TV. Honda and Toyota come to mind...

Our Honda CRV overhang to wheelbase percentage is 37%, as little overhang as as I can make it, wheelbase 103/ overhang 38.

Thanks for all the good advice. You guys have helped me out a lot. Probably won't part with my Buick Roadmaster, but I will keep all this information in mind as I continue to consider size and weight of various fiberglass trailers.

I've had a two mini vans in my time, but living in metro Detroit, they were a Chevy and a Mercury Villager. Honda, Toyota, etc., didn't sit well in the neighborhood

(. . . but I secretly liked the Sienna!!).

The Villager's with the tow pkg were good TV's. The 150HP engine did limit the amount they could tow. We towed with the Villager twin, a Nissan Quest.

After towing a Coleman Rio Grande all over the Continent the Quest went on to tow this for a number of years.... It had over 450,000 klm's on the original problem free drive train.
