DIY compressor with cheapo from HF and 1 gallon tank from Ebay
First I modified the compressor from Harbor Freight: got rid of all the useless plastic trims, removed the switch and fuse holder (using a 16A switch for 30A was a bad idea anyway), installed a barb fitting for the air input and made it watertight. The 1 gallon tank from Ebay got a 100/70psi pressure switch and is filled through the flexible leader hose with integrated check valve. Tank and compressor (with 4 rubber isolators) were mounted on an aluminum base plate. The whole thing fits nicely into the SLS compressor bay (I will use a longer hose to get the air intake above the worst case waterline):
Finally I got it installed today.

The tank is quite sturdy, typically they are made out of 10 gauge steel. I wouldn't expect damage if some small stones hit it other than exposing the bare metal. Otherwise parts like mufflers wouldn't last that long. To better protect it against corrosion is a good idea though, maybe I should spray it with some heavy duty bedliner.

Simply because I had the hf pump already and it fits. The tank allows me to fill it while driving and I have pressure right away when I stop. Most time is saved, because I don't have to unpack it, connect it to the battery, move it around, and let it cool down after use before I can stow it away. I run a awg10 wire into the engine compartment where it is connected via a relay to the aux battery.

I have a small arb mounded in the engine bay above pass wheel well. It's a little more protected in there and shorter wiring lengths. Just something to consider, though this write up looks to be very well done!
