I think they are made in Texas.
Is it a high quality outfit, run of the mill junk or about average?
If these are black with tan or gold pinstriped it might be the same ones I had my eye on.
If so I have seen these trailers in N.E Texas a guy was selling them up in Bells,Tx. For the money they are a cut above most I have seen here in Texas and at $1650 for a 20' car hauler with 16' deck, 4' dove with a steel deck it was hard to beat.
I think I am right about all but look at it to make sure as it has has been 2yrs Not sure what they are getting now.
Standard on the ones he had were full wrap tongue 5"C-channel and frame,
3" C-channel cross members at 16" or 18"(Can't remember)
1/8" diamond plate flooring fully welded around perimeter edges not tacked every foot or so like some. At the time they had competent welder nice good deep welds.
New tires 225/75R15 C-load Hankook tires(Lt. truck tires) (this was one thing I did not like)
Underside was not primed or painted (other thing I did not like asked guy said it was not something I could ad)
5' Rear lockable loading ramps mounted underneath
Had Breakaway kit, 1-brake axle with a 2 5/16 bulldog coupler and 4' extended tongue
When I looked 2yrs ago it was a little under $1650OTD I could not find a trailer that was built as well for the money not sure what they are building now
If memory serves me They also had a 22' equipment/car hauler had 18' deck and 4' dove(reason for the slash Car hauler),16" tires 6" mainframe and 16"-3" cross members 10,4K rating(5200Axles)but was a heavy sucker with the diamond plate floor,Reinforced diamond plate fenders. That was priced at $2450 at the time
Overall I liked them they have plus and minuses just like everybody but the fact about the underside not being done seemed too penny pinching for me and I did not want to do it myself and the fact I found such a sweet deal on a 20' Aluminum hauler that I just could not pass up.
Good luck in your search
Do not do Kearney they on the other hand are a "run of the mill junk" unless you upgrade and option everthing.
