I ran an S185 last fall. Loved it. The one I used was the Gold Series. I was in heaven. Had the AC cranked all day. Just sat back and enjoyed the job. I am leaning towards the T300. Maybe by mid-summer if things keep heading the way they are. Only drawback for me is busting things. Kinda hard to justify spending the cash then fixing when I pay $7.00 bucks a day for an insurance policy when I rent.
The chevy pulls it well, I am in the process of restoring the Chevy mainly as a tow truck for this machine. It has oil, ps, and tranny coolers from the factory as well as a 5.7L. It is a LD 3/4 ton with the trailering and camper packages. The bed in the picture (white) and the black door are for it, then of course some white paint and lettering to match the other trucks. The trailer brakes on both axles help out a lot.
