It is addictive. I have spent so much $ on stuff for my truck, and it didn't even need any of it. Ugh. LED lights, radiator, exhaust stack, A/C, air dryer service x2, CTIS communication attempt (failed), upcoming dump kit, insurance, plates, oil changes, upcoming tandem axle trailer made from same truck, batteries, inverter, generator, tool boxes, fuel cans, fuel filters, air filters, belt, fuel lines, cargo cover kit, rear winch, front level wind (bought-sold), bed crane w/24v winch, radio, amps, speakers, CB, batteries, overhead light bar, etc..... Even just having drove it for the 6,000 miles I have so far, at 10mpg and $2.50/gal for diesel, that is $1500 in fuel alone.
Reach out to other members from your state in PM's and ask what they are doing and at what cost. They do beat-ups here for insurance discussions in public on the board. You probably should have looked it up before you bought the truck, but you already know that now.
