over the years I've used frames like the one show in the link to build trailers that have literally been used on 2,000 - 3,000 mile trips .... the weakness I've seen most often comes when the spring hanger comes loose from the frame .... I've literally seen the metal rip like construction paper .... that is an area where you can't cut strength .... I've seen jet ski trailers with 8" wheels that seem to do well but I don't like 8" wheels for distance towing .... on the trailers I have built I don't like to go below 12" and prefer 13"/14" wheels .... if I was to build a trailer to haul behind an Elio I'd use tires the same as the ones on the Elio .... I'd design the trailer to mount a spare tire that could be used on either the trailer or the Elio .... but then that's just me

Amen to the spare tire for a long trip!
