Yes, you can connect the wiring from a DC to DC charger like the excellent Redarc # 331-BCDC1225D to the outlet in your truck that's already wired to the battery. I also reached out to my contact at Redarc just to be sure there wouldn't be any issues with this setup and he said it will work perfectly as long as the outlet uses a thick enough wire to allow for ideal charging during travel. I have attached a chart that shows the wire gauge you will want to use based on cable length.

I have attached a couple of short videos on this particular charger that you can check out as well.
