An alternative would be to run a 20 amp circuit dedicated to the A/C and plugged into the campground pedestal separately from your existing power cord. You'd have to determine how to wire it into the trailer, up the wall and across the interior of the ceiling to the vent you plan to install the A/C in. Possibly, if there's a floor to ceiling closet or cupboard, you could run the new circuit into the trailer inside that closet, up the back wall and into the ceiling, then fish it across to the vent location. Not an easy task for sure, but also not an impossible dream. Then you'd just have to determine how to plug it into campground power without using their 30 amp circuit. Some have a separate 20 amp plugin, some have 50 amp power and you could use a splitter to plug everything into their 50 amp source..... It'll take some thinking, but it's not going to be impossible to accomplish. Just be safe when designing your setup so you don't hurt anyone or burn the thing to the ground while "testing to see if it works"..... Good Luck
