Once I installed my heater, a lot of stuff in the Frunk had to go: Bigger battery, spare tire, etc.
So I took stock of what I was carrying and tried to reduce it to mostly unique stuff for MY car, plus the usual tools and things and what I ended up with seems to be working, so far, but as yet without any incident that would test it (other than helping out others on the road with spares from my kit).
So here's what's in my Frunk (sorry for the slightly distorted photos - Powerpoint does that):
This is the overall layout, with captions:
I have two tool bags; one behind the passenger seat with my snail gauge, 2 walkie talkies and charger, remote for the stereo (I found it!), stop light prism, LED flashlight, and a few micro-fiber cloths.
In the Frunk, the top left is the fender cover for when I put gas in, then the first aid kit is from West Marine - pretty complete for a small kit and I re-stock the degradeables every Spring because the Coast Guard told me to when I had boats.
The blue box at the top, far right, is the fuse/relay box - it has its' own set of fuse spares and one spare DPDT relay.
The bag at the top, middle of the Frunk ("Hood Tool Kit") has:
Multi-tip screwdriver (Phillips and "-"), tire gauge, spare wheel bolt/nut set, Leatherman Utility Tool (pliers, knife, wire stripper, etc), medium water pump pliers (good for electrical crimps), 36mm Pulley wrench, Metric wrenches in a roll (8-9-10-11-12-14-17-19), Pre-gapped W8AP Platinum spark plug, 3/8" ratchet + 2" wobbly extension + magnetic Plug socket, set of metric Allen Wrenches in a holder, 17mm Allen wrench (for Tranny), roll of blue tape and probably a few more things I've forgotten.
Behind the driver's seat is a scissors jack with lug wrench/crank attached plus a Gortex windbreaker and a few microfiber cloths.
Inside of the round, white spares carrier (it used to neatly fit inside of my Spare Tire...sigh):
More fuses (the fuse box has a full set of spares, too), Fan belt, Valve cover gasket, spare relays, front directional bulbs (unique), Throttle Cable + end barrel terminator for the linkage arm, Clutch Cable, Sump gaskets for VW sump, 12 ga wire roll, Misc hose clamps, Misc. Cotter Pins, Misc hardware nuts/bolts/screws), Misc. VW engine gaskets, spare long plug wire, spare coli wire (unique), Mechanics wire roll, Electrical Tape roll, Points/Condenser, Misc 1/4" "Faston" tabs, misc inline crimp connectors, 2 pairs of Nytrile Gloves, 1 large trash bag (for removed wheel), Plastic fuel filter + hoses + clamps.
When the spare tire got deleted I added a 12V air compressor and a tire plug kit:
I used to have room in the Frunk for a spritzer of detailing spray and a California Duster. The spritzer only gets added in warm weather when the heater isn't used as it fits in the space to the right of the heater body. There is still a little room out there for small stuff (really small stuff), but I have several places around the car where I can fit stuff totally out of sight. I can even fit a decent sized cooler on the back seat!
