I would like to purchase an enclosed trailer to haul two or three bikes. Any advice is welcomed. I've looked at the mass produced 6x10 Pace and Haulmark and a custom built 7x10 Braco. The pace/haulmark appear light duty, but would seem to benefit from light weight when it comes to pulling one. Custom built Braco seem heavy duty but heavy. Is this a concern for a 99 Chevy 350ci V8 tow vehicle?
