Greetings from the Florida Panhandle

First off, welcome to the Forums. We're glad to have you with us.

As to the 2011 Suburban Half ton, you're probably going to want to stop at a 25, especially with a 3.45 rear end ratio.

We tow Lucy (25FB, 7400#) with a Suburban 2500 with a 3.73 rear and a 6 liter. I don't think that a 1500 Sub is comfortably up to much more than that.

Brian

For what it is worth, I recently migrated from a 2010 Yukon w/heavyduty tow package and the same transmission to a 3/4 pickup for our 25' FC. I was not comfortable with it at all (even rigged with a pro pride hitch). I was unable to keep the tranny temp below 205-210 degrees (I think payload was a contributing factor). I understand plenty of folks wouldn't hesitate to go with such a set-up, it's just not for me. And for those who wouldn't hesitate, I have a lovely 2010 Yukon with 10K on it I'd love to sell them!

-Chris

Just went to weigh my Suburban at the local Cat certified scale with a full tank of gas and my lovely wife and this is what I got.

3280 lb on the front axle
3120 lb on the rear
6400 lb total gross weight on the button.

whats left on the front axle is 320 lb and 1080 lb on the rear axle.

factory rates the truck for 8000 Max trailer tow capacity 7400 lb GVWR and 11500 lb GCWR

The trailer tongue weight will be the limiting factor, overall. You'll want to add to the scale numbers above (good job having that!) via the other items you'll carry in the truck.

It's hard to "guess" at a trailer weight when loaded for camping: full fresh water? full propane? what trailer options? One might take trailer GVWR and deduct 15% for a ballpark figure, and use 12.5% of that for trailer tongue weight as a beginning.

An 8k GVWR trailer would be 6,800-lbs at 85%, with a TW of 870-lbs +/-.

If the vehicle manufacturer guidelines indicate that 75% of TW is to be carried by the rear TV axle then about 650-lbs would be added to that axle with "correct" WDH rigging (This assumes that the front axle does not change in height or weight measurements) and the other 25% would go back onto the trailer axles.

1080 - 650 = 430-lbs. That may look good, but it's a bit close if you all want to carry more passengers/gear in the Suburban.

I would insist on a scale reading from the dealer for a trailer with full propane and full fresh water prior to purchase. And agreed weights for any options installed before signing.

Were our hypothetical trailer at full weight, with TW up to 15%, then it might not be a feasible choice based on recommended limits.

8000-lbs, TW= 1,200-lbs (75% = 900) Though the truck shows 1,400-lbs remaining capacity, a 900-lb TW -- leaving 500-lbs overall -- has less than a 100-lb margin on the rear axle IN SOME INSTANCES. With you and wife you are already up against GVWR with a 900-lb TW on this hypothetical trailer at maximum weight. (Are you sure GCWR is 11.5?) Chances are you may never load it that heavy. Or the Suburban. But a lighter trailer -- when empty -- sure gives more room to play around with.

Hard to figure some of this ahead of time in other words. But you are on the right path. Keep reading for other reported weights on trailers you think you might like. The more info, the better.

Brian,

Seems like your in the know for sure as your AS is similar to what I might purchase.
If by chance you've weighed you AS, Do you have the breakdown of weights for your Safari (Lucy)?

Question about the Hensley Hitch set up, How much will it Help or Hinder the 8000 max tow rating of my Suburban

the hitch (a haha) doesn't help or hinder max tow rating.

but since it weighs ~250 lbs, it does count against payload and is part of the gCwr

the UPdated version (a pp) weighs less, and is far more adjustable.
_______

nice to see you've weighed the rig.

IF the burb weighs 6400lbs and the gCwr is 11,500 lbs,

that leaves ~5,000 lbs of towing capacity not 8000.

so something is screwy here.
__________

some of this (towing satisfaction) "will it work, how big" and so on...

depends on how much towing, how frequently towing, where towing and what is carried...

expectations vary as do trip requirements.

cheers

I sure do. Lucy was weighed on a Cat Truck Scale with and without Daisy ('04 Suburban 2500).

- Still hooked-up, the pair came in at 14,060#, 7520# for Daisy (TV scale plate), and 6540# for Lucy (TT scale plate).

- Un-hooked and weighed separately, Daisy (TV) was 6680#, and Lucy (TT) was 7420# with wheels and tongue jack on the scale.

- Lucy was also weighed by herself with her wheels on one scale plate and her tongue jack on a different scale plate. Her wheel weight came in at 6160#, and her static tongue weight was 1260#, for the same total weight of 7420#.

Lucy's effective tongue weight was 840# when when hooked to Daisy with the Hensley weight distribution feature in use.

I hope that this helps.

Brian

Welcome to the group. You asked "what is the biggest..." That is not the same as asking what is the heaviest you can tow. Generally speaking the older trailers tend to weight less per foot. Case in point, my 31' weighs a little less than Lucy at 25'. Asking about biggest (longest) in my mind addresses issues as trailer sway.

Did you intended to inquire about weight? There is a very chart somewhere (searchable) that lists weight, tongue weight, by length, and by year. This would be very helpfull in selecting a trailer after you decide the weight you're comfortable with.

I concur with the others that you'll need to keep an eye on the tongue weight and payload or your setup. It will probably be the limiting factor, as it is for many of us.

Thanks Brien, you are the man. I do have a few questions for you.

What hitch did you use ?

was the trailer loaded with gear and water etc. ?

Looks like it will work with a PP hitch as the hitch limit for my Burb is 1000 lbs with a weight distributing hitch.

although I think it will be close for sure as the hitch adds almost 200 lbs to the GVWR.

We look forward to using the combo for weekenders and possibly a trip tp Fla. from NJ.

This was the issue I ran into with our Yukon. As a family of four in our fully loaded 25'er with the PP, I am convinced I was consistently several hundred lbs over that particular spec.
