Default Towing Capacity H3

Hi All,

Actively looking for a 2007-2010 H3 (non Alpha) for work (towing about a 2k trailer) and PLAY (towing a 3.4k boat). I just need to know if it can do the job before pulling the trigger.

(btw, boat: 2004 Monterey 200LS 5.0)

According to specs, the boat is about 3400 pounds dry (not sure with or w/o the trailer). So I'm thinking that with a full tank, 4 adults, I might be shooting beyond the stated capacity of the H3 (4500 pounds).

We don't go anywhere but Saguaro or Canyon lakes - less than an hour away with only a few small hills.

Will the H3 be adequate for this kind of weight/stress?

Suggestions?

I have hauled more myself it does the job but would not recommend it usually you can get away with a ton over but this would negate any warranties. believe the manufactore always underrate their equiptment a bit knowing people like myself are going to push it to the limit & then some. I usually stay 1 ton or under over the limit anything after that I pull out the big guns F350

So.. I understand it's not going to pull 4500lbs at 65 up a mountain. But what have you experienced when towing?

Currently, I tow the boat with a 2003 Astro:


4.3/190hp @ 4400 rpm
250torque@2800rpm
3:42 gears

As I understand, the H3 (2007 and newer) is this:



The H3 sports:

242hp @5600rpm
242tq @4600rpm
4:56 gears

Cool

You should be good. The trailer is about another 800-1000lbs and you only want to go a short distance. The H3 is rated at 4500 but I'm sure you can tow a good 5000lbs, just not easily or economically.

Thanks Chooch',
I'll certainly be babying it being at/beyond capacity. My main concern is that I haven't done this with an H3 and not quite sure what to expect. Drove an '08 Tahoe LTZ in a past life and had no problem using OD.

With the torque of the H3 such that I can still do 50mph on a 1/2 mile 7-10% grade without putting my foot thru the floorboard? (Yes, definitely using lower gears etc.)


Really like to hear from a redneck that didn't blow his rig trying this..


Thanks

Would not recommend that, do not want to do it again, but the truck did everything I asked of it and got the job done.

Your boat is lighter, and your distances shorter. I brought that boat home solo with some tools and a floor jack. Load your truck up with 3 people and all your stuff, you will be overloaded too.

I think everyone missed that he will also be towing a 2000lb trailer for work too. If that's everyday wear and tear on the poor I5, driveline and brakes will rear its ugly head much quicker than just towing a heavy load one in while.
