Lon Tyler used to sell a GREAT timber/log cart. Light but strong, I've handled green 32' DF 10x10's, alone, once they were up on horses. Lon has sold the business to a nephew & I've lost the new contact info!!
Best to contact Lon @ lon@ltyler.com or 541-367-6726 & he'll steer you to the right spot. There may be pics of it from the LISEC Bayles project.
