running ac or micro unit on tt while parked at home ??

What is of concern when running your AC unit is the amount of voltage drop and that can be easily measured. First of all use your TT's power cord if at all possible as most extension cords will amplify any voltage drop. Turn on your AC and let run for a couple of minutes, measure voltage at any household outlet within your rig. You want to have at least 108VAC or above when running your AC unit, anything less and the risk to compressor failure significantly increases.
