Here are some of the mods I have made:
Tie downs for the front...
Bolted some happi-jack rear bumper brackets to the front bed bolts.
For the rear I installed some forged eye bolts directly through the bumper. On this truck the rear bumper brackets are part of the hitch/rear crossmember. Solid as a rock.
Underfloor storage (Just got around to this today. Still need to buy a latch to keep it shut.)
Makes a nice place to store a table and steps:
12V outlet in vanity:
LED PCB's in all fixtures. All 4 running at the same time draw a total of 320 mA. 8 bucks a pop at Lowes. They are landscape lighting replacement bulbs and are voltage regulated. While bench testing them, current draw and intensity stayed the same from 11 volts up to 15 volts. Wired them up with remote control car battery/servo harnesses and left all the original sockets in place just in case I need to install a normal bulb:
Icebox had to go... I tore it out, put the door and the frame back on the cabinet, and now have space for a larger cooler and all the dry foods. I bought a 48 qt. Ice Cube cooler that just fits through the door. Worked out very well. Now it is like having the icebox and a pantry. Wish I had the dough laying around for a fridge... maybe next year!
