I have a 2011 Zinger 26RL so should be just about like your trailer. I was recently pulling it with a 2007 3/4 ton Yukon with the 6.0, 4.10 differential. The Yukon pulled it well enough but I was not happy with the 4 speed transmission. When pulling in drive (4th gear) the trans. was continually shifting up and down (had to replace a torque converter). If I pulled in third gear the engine RPM was around 3200 and the MPG went to about 8 MPG. I might have been better off with a 3.73 differential. The previous owner pulled the Zinger with a 1/2 ton Ford. I traded for a Toyota Tundra, haven't pulled the Zinger yet, Just got the hitch set up today, we'll see how that goes.
