I'm lovin the build and truck so far!! And I shure am jelous of the roatry,I had originaly planed to do a 12a or 13b but stuck with the tiny 13j just for the coolness factor of the tiny motor,but that thing is not worthy of the interstates as I found out this summer,lol, also u can roll 16gauge,it takes a few times threw the roller but it will be crazy sturdy when done,I also cross braced mine the other direction to keep away from any flex
