2007 GMC Savanna CV 4.3l and GVWR Questions
I own this van. 2007 GMC Savanna G13405 I would like to be able to tow a small travel trailer, not a popup. I understand that there are very strict limitations regarding the weight of the trailers ...

Okay, we purchased the 2015 Winnebago Micro Minnie 17ft 1705. Dry weight 2750# and the GVR is 5500#. The Savana van weighed out on the local truck scale at about 5300# with me sitting in it. I added a B&M Supercooler and a tranny temperature gauge. The supercooler made a big difference towing with this rig. I added a Equalizer hitch and we probably add about 4~500# in camping supplies. Fill the fresh water tank about 1/3 to half.(12~15 gal)
We have taken a couple local trips and the transmission temperature has been very stable at around 160*, stop and go city driving, and the highway can drop as low as 140*. So I'm not worried about overheating the trans. The 4.3l GM v6 does struggle a little with pulling up hill ,a little doggy but not as bad as I feared. But it does okay if I have to put the spurs to it. The transmission guys explained that as long as I keep it out of overdrive and in 3rd with tow/haul engaged, I should be okay. He said the 4l60e GM trans has 4 plates for each gear up to 3rd and overdrive only has 2 and it can be really easy to burn out the OD pulling an oversized load.
Over all a lot better than I expected.
Thanks for all the feedback.
