derek_gardner, in 2009, had I known I'd be in a position to purchase a trailer in 2012, I would have likely bought a bigger truck.
Since I couldn't afford both, I did my homework, very happy with my purchase. I'm right at my rear GAWR, within 10% of my GCWR. It tows well, brakes well. I know I won't go to Colorado, but have 10 more years of work before I can retire, so don't have the time to be on the road long enough to get there.
I've been all over Texas with lots still to see. Davis Mountains in West Texas, Palo Duro Canyon in the panhandle (with its 10% grade in/out ... no too long though). The weak link is holding 65mph with a good headwind, lots of dropping to 3rd gear and winding up the engine to 3,500 rpm! I just find a slower speed.
All in all, I'm happy with what I have. At my current rate of saving, I'll be able to pay cash for a 3/4 ton with diesel in a few years. I'll get there!
