Is it a full size truck? If so then you can add a second battery easily by utilizing the space the factory would have put it for a diesel engine (those all come with two batteries) or the factory camper/plow package. My truck is farily new so I had to buy the tray from a dealer for about $30. Then every couple years I buy a new battery and put it in as the primary and move the primary to the secondary and turn the old secondary in for the core. I'm using an isolator which is basically a couple big diodes to prevent one battery from discharging the other but allow them to both charge. This gives two advantages, one I can jump start myself if needed and 2 if I ever were to be stuck/stranded someplace I have extra battery power to run all the gear I keep in the truck.
