I-10 was no fun. Went through there this summer with a Harley in the toy hauler, it is the one and only time my bike has fallen over while towing
. It is tied down on four corners plus a chock mount holds the front wheel and that stupid bucking bronco pathway that they call a road defeated my mounts. Not to mention it just became very tiring porposing for extended periods of time. They make great Po' Boys, but the roads could use some work.
Best of luck to you, hopefully you can find an alternate that doesn't take you too far out of the way.
