#44 of 63 Re: Pulling 3900 lb travel trailer with 2008 Suburban LT [kiawah]
Jan 04, 2010 (8:59 pm)
Well, I have purchased the 100k bumper to bumper and the vehicle only has 32k on it. The powertrain has the 100k warranty anyway. I have only pulled this trailer once since I bought it in October. I would only pull that distance probably once per year. My main concern is that I am pulling too heavy a load for a Suburban with a 5.3 liter. I believe the transmission is the 4L60E. I know it's the 4 speed and the rear end is the 3.73. The book shows 7100 max trailer weight which is considerable more than the 3900 I am pulling. I realize you have to take account for cargo, but I am not loading it up hardly at all. Leaving the water tanks almost empty till I get where I am going. I am just trying to see what people's experience has been with the newer Chevy Suburban transmissions. Thanks.

I had a 2008 Suburban LTZ with the 5.3L and 3.73 rear end 4X4 and tow package (trans-cooler, etc). I towed approx 5K-6K lbs back and forth from OH to FL with no issues. Used the trailer mode. If I tried to stay on the gas to keep at 70-75 MPH, RPM ran in in 3200-3500 RPM range (3rd gear) and gas milage was terrible (<8 mpg). However - transmission temp never was an issue. I now have a 2009 2500 LT 4X4 (6L, 6 speed, and 3.73 rear end, and trans-cooler, etc.) and tow approx 9K - 10K lbs back and forth from OH to FL with no issues. Used trailer mode. Run in the 75mph range at approx 2200 RPM range and averaged just shy of 10 MPG. Trans temp never was above 150. Looked at 2007 2500 with 4.1 rear end - gas milage was terrible all the time, and RPM towing was back over 3000 RPM. If you are only pulling 4K lbs - you should not be having any issues ... Very happy with my '09 2500 towing ability ...

Thank you for your reply. I am going to install the cooler before I tow again. I actually averaged about 10.5 to 11 mpg for the whole trip with the mountain driving included. I really had no issues other than the temp going a little high a couple times. I had some people tell me that 220 was not too high and the computer would shut the thing down if it got too high. Interstate driving at 60 to 65 was between 200 and 210. The dealer service tech said he wouldn't even worry about it but a cooler wouldn't hurt. I am not sure how yours was at 150 because GM says the normal operating temp is 180 to 200. I am reading mine with the onboard display that came on the vehicle. I have heard that depending on where the temp is sampled has something to do with what a guage may show.

If I remember correctly - I think I was also at the 210 - 220 range in my 08 LTZ when towing even with the towing package cooler ... but I am at 150 - 160 in my 2500 ... different engines and different coolers - so not sure I know why - simply know what is showing up on my dash readout.
#48 of 63 2009 Suburban Towing capacity
Mar 16, 2010 (4:31 pm)
I have a 2009 Sub LTZ. I bought this thing and fear that I may have been "had". It did not have the K5L HD towing package, so I had them change the rear axle from a 3.08 to a 3.73. I was told the K5L was simply a different rear axle and a heavier-duty transmission cooler. I was clear that I wanted to tow a 5000lb dry-weight trailer. I have asked 10+ people this question and I have gotten 10+ DIFFERENT answers. Can someone provide some advice on what i should be towing with this thing? The manual says that the 5.3L with 3.08 has a tow max of 5100lbs, with 3.42 a max of 5600 lbs, and with the K5L a max of 8100 lbs. Any help would be greatly appreciated. Thank you- Steve

I know what you mean - I followed a bunch of forums and always had different answers in trying to decide what I needed (even though we all know more is better). Not sure what all changed in the rear end when you "upgraded" the rear axle from the 3.08 to the 3.73 - however I would have never pulled 6K with the 3.08. Variables in towing specs all include engine (5.3 vs 6.0), rear end (3.08 vs. 3.42 vs. 4.10), 2WD vs 4WD, LS/LT vs LTZ (autoride), wheels (20" low prifile vs. normal), tow package, and how much "addtional weight" (people/gear) you have in the truck, etc. Most likely your hitch is a class III and good for 600lbs tounge and 5.5K - 6K lbs towing (that is the standard on all the Suburbans as far as I know). My previous 08 Suburban was 4x4 LTZ (3.73 rear end), autoride/level, 20" wheels, heavy duty trailer package, and 5.3 engine. 6K was right on the edge of what I would comfortably want to tow with that car. Depending on your distance, and if you are really at only 5K on your trailer (go to a scale), you might be on the edge. You will feel it back there. Hope this helps.

Thanks for the reply. I'm not so sure the real axle was "upgraded", but the change from 3.08 to 3.73 should enhance the towing capacity. I am under the impression that the Sub suspension is not different when the HD towing package is added (only an upgraded tranny cooler and 3.42 gears). In fact, it is not a very expensive option from the factory.
I think i'm just going to rent a 25ft trailer and get a feel for it and then i'll probably end up sticking to a 4000lb-4500lb target weight for a trailer. I think i'll be within my range for sure. Thx again for your response.
#51 of 63 Towing problem with a Tahoe
Mar 18, 2010 (6:32 pm)
I have a 2008 Tahoe LT2 2wheel drive, with towing package. Last summer, we towed our 4600#trailer and it about over took the Tahoe, the trailer fishtailed and the Tahoe was rocking. We were all over the road. Since that incident, I purchased an additional sway bar, load leveler, the works. The trailer still sways behind the Tahoe and causes the Tahoe to move sideways. I can't go over 45mph when pulling the trailer. The max tow cap. is 8700#. Had a friend pull the trailer with Silerado, no problems (went 75mph). So, I know it's not the trailer. I spent hours at a hitch shop getting the right set up to make sure the trailer is level, tongue weight ok,etc. Any suggestions would be greatly appreciated.

I go for the longest wheelbase vehicle I can get, for towing.

We have a 2008 Tahoe LT (4x4) with the 3:73 gears and the 5.3Lt. It also has the tow package. We pull a 29ft (33ft front to back) Keystone Passport 290bh which is 5,100lbs dry and has a 500lb hitch weight. Our hitch is a Reese with the weight bars and a slide sway bar. I have left the sway bar off at times and i know its not there, but nothing that would scare my wife or I.
I have pulled this camper 70+ mph down the highway, but usually run around 65. Put the vehicle in 3 and press the tow/haul button and the vehicle will pull this camper great. I am actually looking at a bigger one weight wise. I don't dont know why yours would sway that bad? Is it possible that you are loading all your gear in the front or back and not distributing the weight in the trailer? Wish i could help, but mine seems to do the job very good.
