2009 suburban towing update
Hello all,
Just got back from a 2 week 3010 mile trip with 2674 miles of it towing a 30' travel trailer weighing in at about 6800lbs. The trip was from San Antonio, Texas to Anaheim, California then to Oceanside, California, after that off to Balmorhea, Texas, then home. The toughest parts of the whole trip were the grade in Sierra Blanca, Texas, The pass near Thousand Palms California, and the grade on HWY 8 from El Cajon to Ocotillo California. Thousand Palms was really bad because of the headwind we got the second highest trans temp there at 235 degrees with an outside air temp of 106, the highest trans temp we reached (242 outside temp of 110) was on HWY 8 in El Cajon I did not think that hill was ever going to end. I was really impressed the suburban ran nice and cool in 116 degrees from Tucson to Palm Springs. MPGs pulling averaged about 9.9 at about 60mph and 2500rpm. However, the last two fill-ups from Balmorhea to home we averaged about 6.7 mpg at about 70mph and 3000rpms. I know I pushed it hard the last bit. Now to give her a few days off then change all the fluids and flush the tranny.

Yes, the only time we had any issues was in Pheonix 119 degrees and the sun beating in the front window we had to put the sun shade on the dash for about an hour of the drive until the sun got higher and was not comming right in the windshield. the kids in the back were freezing but the front seats were hot even the seat coolers were not helping. Time to tint the windshield.

I never use the AC when towing with my 2002 Tahoe (26 foot travel trailer). It seems to suck too much power and of course it makes the MPG even worse. But, I also dont have to deal with temps that high!

I found that the 1500 Suburban towed a well as my F250 with the 6.0l Diesel through the hills, flat land the diesel would out pull the burb. That 6.0l would have puked then blew both head gaskets going through the pass at Ocotillo if I tryied to do over 40mph for sure (I know because it did that going through Kerville). Now that I have replaced the 6.0l with a Cummins I have not tried to pull the trailer yet (still working out the bugs) but from now on the long hilly trips will be left to the Fummins even though it is not nearly as comfortable as the Suburban. The Suburban, I will use for local towing (4 hours or less trips) and flat land trips.

when towing my bigger boat (total 5,000 lbs) and have the burb loaded up with all the luggage and family going to NH, 5 hour trip, the only prob I have is one big hill in VT. I can do 70 just fine, but its in 2nd gear @ 4500 rpm. Boy it gets loud and annoying. I passed a ford f150 carrying a small load of wood with ease lol.
Also, sweet upgrade, got rid of the powerjoke and got a true diesel, a Cummins! Should haul *ss compared to the 6.0l

Indeed, thanks for the update do you have the aux trans cooler?
Never could understand why auto manufactures don't apply a UV coating to the front glass... there has to be something that can be applied that won't interfere with vision night or day but will help block the heat..
Love those cool waters of Balmorhea SP ever do Fort Davis and the McDonald Observatory? We did a similar trip a couple years back.. took I-10 all the way to Anaheim (Disney Land) but we came back via I-40 for a different view on the return

My 02 burb had a slightly tinted windshield with a tall blue strip at the top. Loved it. I really miss that in my 07. Also, the sun visers, my 02 when pulled them down and put them to the side there was a smaller secondary one to fold down as well. That really helped with long road trips because of the twisty roads, I hate d*cking around with the stupid design of the 07. So just bought good sunglasses. Boy, gm really took away some great features for their newer burbs...
