We tow a Bighorn 3160 with a F350 SRW crew cab. Our loaded weight is 13,500 and we do not exceed any rated load or towing limits on the truck. We towed it over 2,000 miles this summer and it was a delight. We don't full time But many Bighorn owners do. I'm not sure about such extreme temps. The yeti package will heat your tanks (never turn on if the tanks are empty). There are people who do spend very cold winters in this trailer. We also have the factory ST tires for now and have had no issue with them either. We have a TPM and carefully watch pressure and temp.
