im with nick.
hear your concern mike- if i get stopped with a big truck / big trailer / camp gear / wheeling stuff id hope id have a chance at educating said officer about R permit and Recreation.
If you get pulled over with 3 of Aries cars on a trailer, you would be F'd for and rightfully SOL.
you with mule, troys buggy, coolers, camp gear, again- i think you would be find to show your over weight, have a recreational vehicle endorsement and are fine. (assuming GVW's are not exceeded)
