I pulled our 25FB for 8 months with a Yukon with the 5.3L engine, 3.73 axel ratio and a factory towing package and did fine. Out trailer GVRW is 5500lbs and the Yukon was rated to tow 7000lbs. I add will the hills were a little tough though and didn't break any climbing records.
I traded the Yukon in for a 3/4 ton p/u and pull that trailer around like a toy now.
I also have a weight distribution hitch with a sway bar, it just handles so much nicer. The most important thing is to check your weight and make sure you are within your limits.
