I'm converting a 32 ft. uhaul truck into a camper. I want to install my 3000 watt inverter to run the Frig. while I'm on the road. I want to install the unit about 18 ft. from the battery, what size cable would I need from the battery to the inverter.

A very thick one,,,like a baby battery lead on your car,,,its a very bad idear to have it so far away from the battery point, you would be far better off finding a closer place to put it as the volts drop off would have a big drop in out put on the inverter,,,also thats one big mother of a fridge to use 3000 watts????
you need a small power station to run it,,and if it do use 3000 watts your inverter is far to small to do the job, read the out put plate on the inverter,,it says 3000 watts max? not all the time,,,,thats about 2000 watts realy running contently and the whire to feed the inverter will need to carry about 30 amps so your car battery is say 90 amp hours plus the volts drop off, you would be lucky to have the inverter running for 3-4 hours before your battery go's is very flat on you!
