Towing

[Yukulele]

I just bought my first 1998 GMC Yukon with 118xxx on it. I plan on towing my Jeep cherokee about 400 miles round trip to Rausch Creek to go 4 wheeling. First i need a trailer which im planing on an 16'-18' open deck trailer prolly weighing around 1500+lbs and the jeep is about 3500lbs.

How do you all think it will tow? what would you suggest? What have any of you towed before and how long?

Thanks
Mike
