Suburban 1500

We've got a 2002 1500 Burb and are looking at a 22' Safari. I'd like to hear from other 1500 Burb owners regarding what they tow...I know we've got a pretty decent weight limit, but is 5600lbs too much for the 1500? I believe our limit is 7000lbs-maybe a little over. Thanks in advance.

Rear end gear?

Do you know the rear end gear ratio? It may be 3.73 or a 4.11. The tow rating is different for each ratio.

I have a 2500 Suburban to pull our 27' Overlander (6060#) loaded. Since we have the 3.73 rear end our Burb is rated for 7400#. Our Overlander is 81% of the max rated load.

I think you'll be fine with what your doing. If you started to break the 6500lb range, I'd want to make sure you had 3.73s, but given your size, weight and wheelbase I would think that whatever you do with what you've got, you should be fine. After about 6000lbs though, you're starting to venture into 3/4 ton land IMHO. My 1/2 equiv sedan w/ 2.93s was rated at the factory to tow 5000lbs.

I don't think you need to worry about having 4.10 gears in it, not that it would be a bad thing if you had them, but I don't think with your load you'll need to worry too much. I know the trans would be happier w/ 3.73 gears in the back, but to be honest, even 3.42s would be find for what you're doing.

Thanks for the responses. DH has the truck now and when he gets back, I'll give a look and see if I can find out what we've got. I just don't want to fall into "the cycle" of bigger truck/bigger camper- !

Inside the glove box, there is a sticker with a bunch of odd looking numbers. They are called SPID coded. The link below has a list of what each of those codes are. I know it says for Caprice, however GM uses a lot of the same codes across the lines. With this list and the sticker located in the glove box area, you should fairly easily be able to figure out what factory options your truck has, provided it has not been modifed.

http://www.capriceclassic.com/spids.html

I have a list of the complete GM SPID codes, but it's too big to attach or cut and paste into this thread. If you need me to look one up, let me know.

1500 burb

We have a GMC Yukon xl. When we purchased it back in 2001, we purchased the 3.73 rear end with the 5.3L engine. We towed our 30' Classic for a couple of years. For that year, I believe the 3.73 had a tow rating of about 8,000 lbs. The 4.10 had a tow rating of 10,000 in 2001.

I transferred out the 3.73 for a 4.10. What a difference. We now have over 30,000 miles towing the rig. It gets a little slow at 11,000 feet in the Eisenhouer Tunnel in Co. But other than that, we can tow all day long at 62 miles in OD. The tranny doesn't do excessive seeking and nothing overheats.

I maintain the TV very well. Tires, brakes, suspension, tranny, and engine are in excellant condition.

You should do very well especially if you have a 4.10 rear end.

We own a 2003 GMC Yukon XL 1500...

...and have a 25' Safari. NO problems whatsoever - even going up the 10 into the desert (from Indio) we've maitained a 45-55mph speed.

I have a '98 Sierra Extended Cab 1500 with the 5.0 engine and tow a '59 Trade Wind at appr. 4000 pounds without any problems. I don't know my gear ratio. Would this be listed on the sticker in the glovebox for my older GMC too?

Found the original sticker-we've got 7000lbs GVWR, the 3.73, and the towing/trailer package. Looks like we'll be okay for the 5600lbs gvwr of the 22'!

Thanks again for your replies.

Brad, it should. If not the glove box, maybe under the hood, but on the Burb it's typically in the glovebox.

Should be fine..

We have towed a 6500# Excella 25 (narrow body/heavy furnishings..) for over two years with a '94 Suburban 1500, with only 200 hp and 3.73 axle.. Chevy Brochure claimed it was rated at 6200# GVWR, and yet window sticker with heavy duty tow package claimed GVWR of 7200#. It tows well at 60-65 on level or downhill, kinda slow uphill, but long wheelbase and anti-sway take much of excitement out of towing... Keep tires pumped way up on Suburban, and all should be fine... Towed a 23' Nomad trailer (5600#) for 10 years and 30K miles before buying the Airstream...

John McG..

>> Though we did just upgrade to 2002 Excursion with 4.10 axle, air bags and other goodies...

Exclamation

Okay....Our hitch says w/o a wdh, our trailer weight should NOT exceed 5000lb. (which its gvwr is 5600lb.) and the tongue 500 (brochure reads it's 510 w/o options)....WITH a wdh-12,000lb trailer/1200lb. tongue.

Do we need a wdh? My guess is yes, but I'm not sure.

We NEED a sway bar.
We NEED a brake controller.

THANKS!!

You need to use the weight distribution with the hitch. If I recall correctly, the 22' units (at least the newer ones) weigh over 5000lbs. Yes on weight distribution, yes on brake controller and a heck ya on the sway control as well.

Could you get by without weight bars? Perhaps, but to me, the weight bars do more than just distribute the weight, they help make a more robust connection that adds rigidity to the hookup. In your case though, your hitch needs to have it since it won't deal with the overall weight of your coach without it.

Yes, understand now how the wdh works! The gvwr is 5600lb. on the 22'. I think we'll have the dealer do ALL the work that needs to be done for us to pull her home- -that way, there should be NO question of what we have or are missing!

Be careful. If the dealer is a good one, great, but I did the same thing and let the dealer do the original hitch install, with weight bars, etc. Check with the hitch manufacturer and here to make sure the dealer is getting you the right weight bars if you have any doubts he/she is getting you the right gear.

I found on this forum that there is such a thing as being overhitched. My first hitch buying exp showed about a year later I was severly overhitched with 1200lb bars with a Bambi and a 1/2 ton equive tow vehicle.

I now run smaller bars and may even go smaller still.

hi five and others

selecting wd bars is pretty simple.......and based on tongue weight.

this is my understanding......

if 600lbs on tongue......600lb bars
if 800lbs on tongue......800lb bars
if 1000lbs on tongue....1000lb bars.......

bar ratings mean that when fully tightened up,
bars can redistribute the 'rating'

in between, opt for next rate up unless the t.v. is so heavily sprung as to not need wd bars anyway.....then go with lower number.

based on "loaded" trailer tongue weights not empty weights...so the trailer is full of crap and the lp tanks are full. moving cargo around can change tongue load significanly....goal is 10-15% of total loaded trailer weight.

gotta go to the cat scales and measure t.v. axle weights with bars engaged to confirm sizing and set up. with the higher rated bars they may not need to be fully tightened....and if bars selected are underrated they may not ideally redistribute even when fully tightened.

cheers

We had a 2001 Yukon 5.3l/3.73 towing a 21ft Sovereign. Loaded weight is around 5000lbs. Towing was fine in the Mid-West, but less than a joy in the Rockies! We slowed to 22mph on some of the climbs! Not something that I would recommend. We sold the Yukon and went with a Sierra Denali AWD, 6.0 l, quadrasteer & 4.10 differential. Night and day difference!!

Several WDH choices..

Someone will undoubtedly wiegh in with Hensley Hitch recommendation, which I think a little much for your 22' Safari, but there are also other choices...

Reese and others use spring bars to provide anti-sway stability as well, while Draw-Tite (I think..) uses spring bars solely for wieght distributing, and separate friction bar for anti-sway... There are numerous searchable threads on trailer weighing (using truck scales) and booster springs etc to provide more background, but you should be fine with almost nay WDH and anti-sway setup and the 1500 Suburban..

Looking forward to pictures and a report when you get it home from dealer..

I'm looking forward to being able to post pictures and giving a report- ! We did find storage today, which was a big load off my mind. We also have found our wdh but the sway control is separate. Probably heading up to Camping World on Tuesday to pick it up-well, that depends on what the dealer down in Tampa comes up with-we told her what we need, so we'll see what she can do for us.

Thanks for the tip SilverTwinkie. I copied down all the numbers from the tag in the glovebox, only 55 sets of them, and checked with your Caprice link. Found out I have 3.42 gears, 100 amp generator, 4L60E transmission and 6200 GVWR plus a few other items not as interesting. Been wondering about this for a long time. Kudos to you. Thanks.
