This link is our 20’ dove tail we pull. Which looks similar to your link Brian. Only we have the 8 bolts axles, the link shows a 6 bolt pattern like the one your looking at Post 1 with 16” tires.. They are built heaven. We haul a 10800+ lbs Deere tracked skid loader around with it. IRC, it was just under $5000. We have the one the hidden ramps and not the flip downs. This is the one I can’t get my T/A up one without finding a ditch.
The car trailer that I prefer is a H&H speedloader. They have a nice web site. Trailer mfg is regional, some are owned by some nationwide companies. I think H&H might have some sister trailer companies. We have a enclose H&H too. The H&H 18’ tilt bed is a lot cheaper, mid $3000s.
