Recently moved from San Diego area to Nevada, (about one hour south of twin falls). I have been very happy with my BFG A/T, the biggest factor in traction is size of the tire. I have 285/75/16, and would not go any smaller. I usally get around 30-40,000 on these tires. Now they make them in a load range E with a rating of 3700#s per tire, if you tow. If you shop at Costco they sell for around $200 a piece. Anyway hope it helps. Casey
PS I have a 4 horse trailer for sale... PM if you are interested.
