I just purchased a 16 ft tandem axle flat trailer with a beaver tail to haul my T and/or A around. My tow vehicle is an older Chevy 1500 Silverado Z71 4x4 off road extended cab.
It took me over 2 years to find a trailer in good condition that I could afford.
I checked Craig's list etc. and got lucky by keeping my eyes open.
A small construction company near my work put it near the end of their driveway with a hardly visible For Sale sign. After a couple weeks I finally stopped to see it.
It was taking up room in their yard and they just wanted it out of the way.
I got it for an amazingly low price because they didn't want to be bothered with the trouble of advertising it.
It is a bit heavier than I was considering (10,000 GVW) but has brakes on both axles, built in ramps, and a spare tire.
