I tow with a 2001 Express
 

1500. Upgraded the hitch put airbags in the back and an extra transmission cooler. Mine has the 5.7 and I tow my 25' Rage with seven of us and all our stuff. I'd love to have a van like that!

Yep.
 

Already has a class III frame hitch and may even have the towing package haven't really had time to check. Been parked since last Sunday when I bought it.

Here's a pic of my old e-bay baby. That boat, loaded was 6600. Had a blast w/this thing! Pulled that Sonic @ 70 on cruise all day long. Cols to Lake Erie every weekend (2 1/2 hrs each way) and in between, Ohio River and Rice Lake in Ontario.
Went to put the crate motor in it when the experts told me I had to tear the entire front end off to do it!. I said screw that, It's a $1K van!
I pulled it through the drivers door ;)
If that van could talk ;) Almost as good as my old company car that had toe prints in the ceiling that my boss noticed one day while riding with me :cartman:

All that weight in the van like passengers and stuff subtracts from your overall gcwr. I don't know what your tow rating is, but you may be over your gcwr, while still under your tow rating. Max tow rating is calculated with an empty tow vehicle; only a driver.

Your tow rating is 10,000 lbs according to the tow guide.

Wannabe

parents hauled our boat and trailer around as a kid and that thing was great. I even used once or twice and was a great vehicle. And you have a 3/4 ton frame with a diesel that 21ft boat will be like a utility trailer. Heck a chevy cruze would tow that boat fine probably weighs all of 3000lbs

fully loaded with coolers and fuel is around 3800 plus the trailer.

a colorado could tow that youll be fine

I'm within the range but...
 

it's just not good towing that close to the margins. No close calls but the most important people in the world are inside. My boat is 3700 dry. The van you bought is great. If I could find one with the low top leather conversion I'd buy one instead of a newer truck. Fantastic for traveling in comfort and taking folks with you.
