Today, none of the US commercial hitch manufacturers anywhere have an aftermarket hitch for Smart. If they did , probably would be in the 100-250$ range bolt on.
Until a commercial hitch gets made, there won't be anything coming out of a US plant. But, customs are still being made at our Home site in Phoenix .. and other fabication shops.
U-haul has a custom fab shop in Phoenix.. 1-800-234-8869 then #2 for custom hitch. If they make it for you, they give you the hitch and maybe send the design over to a commercial maker for wider distribution.
If you have one made, aslo get the design for this forum.
$400.00 for hitch and installation ( I know this is high-- still not the 600+ canadian model)
Other hitch manufacturers might assist to design and install a custom hitch. Any or all of the following do the commercial designs for the US market.
Thule/Valley 1-800-344-3230x3x127 Califormia and?
Curt 1-800-738-7213 Wisconsin
Reese/Drawtite 1-888-521-0510 Ohio- California and?
I have been trying to get reasonable hitch installed for a few months.. The custom shop is the only way so far.
