I pull a 7' x 16' Interstate LoadRunner enclosed trailer with my 95 GMC Sierra 1500 (v8, 350 as well). Granted, I get about 8 miles to the gallon on a good day, but I've never been in a position where I couldn't get somewhere. I run a VERY tight route, no more than 2 miles in any direction, and never get above 50 or 55. Someone with a longer route, higher speeds might have a different experience with that type of truck/trailer combo.
I'm a Stihl handheld guy, with Toro push mowers, no brand loyalty on bigger mowers. You couldn't pay me to own a Ford or Dodge.
My business provides quality lawn care, but more than that, we offer even higher customer service.
