Well lots of ideas already but for me mounting them on a wall works best. Place on a wall were they are out of the way but you can get them without car damage if it is loaded. The big hint is make a wooden block/ramp that you can put in front of a good wheel and pull trailer up on the ramp for tire repair. I carry jacks but it is so easy to just drive it up on the ramp to lift the flat wheel for changing. Make it short enough so it fits between axles. WAY Easier than jacking it up and quicker repair too.
I have a compressor mounted in the trailer but a cylinder of CO2 or Nitrogen set up is surprisingly inexpensive if you check around and buy used items. You can mount it against a wall also and a 50 to 100 foot hose is pretty handy. Refilling a CO2 tank is like 10 bucks and last most a year or better. For another 50 bucks you can get a small solar panel to mount on the trailer roof just to keep the batteries topped off and the batteries will last longer if they are kept charged. Wire batteries into the tow rigs charging system but install an RV type isolator. Jeff C
