I am about to buy a 2008 Supra sunsport 22v and wanted to make sure my Tahoe would pull this. It is a V8 but not a Z71. It has a tow package on it and has pulled my 2001 Moomba outback and I have also pulled a BMW M3 on a very heavy trailer. So do you think I will have any issues pulling this boat?
Heath, I have the same boat, and just sold almost the same truck. I had an Avalanche with the 5.3L, as others have said... you will be fine! Good luck with the new purchase!
It will pull fine if its the 5.3. With gear, 6 passengers, 24" wheels, 21.5 ft boat and 3.73 gears our tahoe does lag a bit pulling through long grades. Although, it works for our needs.
My buddy pulls a 21SSV with a 6cyl Nissan Frontier with no issues. I used to tow my MoombaLSV with a Jeep Wrangler, no issues. Your Tahoe should handle it like a champ.
Another vote for the tahoe. I have a 5.3 in my tahoe and in my silverado and both tow fine. Although the Tahoe has the higher gears so it does a little better on the grades but sucks the fuel.
I have the same two tow rigs as Newty but my Silverado has the higher gears.
Don't run overdrive when towing and run it in tow/haul and everything should last. When you are going up a good grade pull it down into 2 and run it up to 4k RPM. Mine do pretty good if you do that.
