Eric, ol buddy, you don't need another truck, you need another project. Wow, that thing ever tweakered out. You get another vehicle, and the process is going to start all over again. BTW, all those thousands of $$$$ you spent on mods, are pretty much thrown away if you trade it to a dealer.
Unless your house is paid for, you're debt free, you have a seven figure 401K, and are going to pay cash for the new project vehicle, no, you don't get a new vehicle.
But Yes, I would sell that truck if I was you. I'd use the money to get out of debt, and buy an old Toyota Carolla. After you're completely out of debt, you save up the cash to buy a new truck. Trust me, you spend Your own money, not the banks, and things mean a whole lot more to you.
That's just my opinion. You do what ever you want.
