I have noticed in many post profiles that some use a #5, #6, #11 etc. Judging by the use in the membership they seem to have a pretty solid endorsement. Looking at the TST web site it doesn't discuss the different sizes, their applications or their specs. My 12V is basically stock and I would like some more towing power on the hills, not a lot as I only pull maybe 5k. Any discussion would be welcome.
