Sac to San Diego will be more than 8 hours.. better fly.
if ur into sitting in traffic and long commutes as well as $5-6 dollar gas then ur good, not to mention rolling blackouts and at least 500k home or rents in the 2-3k a month range than Cali may be for you…. Also, hunting suks here and if...
I would use what you have until u get a new truck. I have a 3/4 ton Ram Cummins and it pulls my 30’ over grades easily, and the exhaust brake is priceless. I would take a chance on breaking things if they are working for ya…. Good luck.
