I have a 2005 Silverado K1500 with a 5.3 v8 and 4.1 axle ratio. Manufacturer book says max tow weight is 8600 lbs. I want to buy a travel trailer...preferably 26ft. What approximate "dry" weight ...
I recommend 5k pounds dry. That will be around 6k loaded for a week long trip whether is has 10k GVWR or 6k GRWR. From that era, the 4-spd transmissions really limited comfortable towing experiences compared to today.
Flush all your truck's fluids. Get a WDH with integrated sway control and a proportional brake controller. Happy Camping!
