He towed it with a SRW 3500 Chevy and upgraded to a duallie.
I quote from him.
"These larger trailer being so tall now 13 feet and with the manufactures moving the axles back more and more to put the weight on the truck to save a buck on tires is not a good thing and is making a very unstable environment while towing. Check your weights, do the research before you buy. These trailers are getting very heavy!"
