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 ...

I towed an ultralight 25' TT RV with a 2000 (or 2001) GMC Safari AWD. The RV was about 4900#. The 4.3L really struggled with the excess wind drag and weight. One time it overheated (puked coolant) when I stopped to fill up after fighting a headwind. I think the same engine in a full sized van will REALLY struggle towing an RV.
Yeah, that's a lot heavier and bigger than I want to try to pull. I think I can keep the total trailer weight below 4000 with about 400 for cargo. Weekend trips mostly, no more than a couple hundred miles.
I figure if I use a weight distributing hitch along with a supplemental tranny cooler and a little caution I should be ok. But you're right. Even with that it'll be a dog.
Anyone tried upping the HP of the 4.3 a little with a hotter coil or a chip retune? I figure if I'm riding the raggedy edge I might as well try other things.
My problem is that this van is primarily my work vehicle and it has been customized to that purpose. I'm willing to open the pocket a prevent having to replace it. I've already looked at the SC add on but I think that would be a little over the top.
