Benny I don't know if you ever mentioned this, but do you plan on running this in an urban/suburban environment with people everywhere or you gonna try and rent spots out in the country? The whole idea of stealth is gonna be a moot point if you have a trailer with a condenser running in the back yard of a house in the burbs. If thats the case I think it'd be a cool idea to put the compressor close to your house and set it up so it looks like its just part of the mechanical for the residence, then dig a shallow trench and run your lines out to the trailer underground. Use compression fittings so you can unhook in a hurry and worst case you lose a little line set, best case is you have a day to dig it up and bounce but either way it'd prob be less suspicious to the neighbors
