Yes it's much much cooler in the northern Florida panhandle! We had a delightful sweaty 85F in Key West last week and tonight we have 30F in Destin! Got two heating systems running - the Airstream has a propane furnace which we pay for the propane and also we connected up an electric space heater with its own thermostat hanging in the middle of the van and plugged that into the campsite electric system so that's covered in our $40 night fee. Spent the last 24 hours figuring out many electrical problems and replaced main power cable to hook up, replaced breakers and added redundant systems to bypass the Airstream sophisticated built in electrical system so we can survive a cold night in comfort! Learning to adapt as failures occur all around.... AC and heat pump were already dead and will be fixed under warranty when we return to VA later in the month, fridge is oscillating up and down wildly but we have it tamed now by adding additional clip on fan to cool the evaporation coils.... then the power system developed all kinds of issues and we bought a 100 ft cable to borrow from neighbor power supply which just kept us going overnight last night except the rain and moisture kept tripping out GFI breakers. Must have stopped at 5 or more stores yesterday and today to find all the parts! Tonight (so far!) all systems are running perfectly!
All part of the rich life experience so you are better prepared for the next crisis ! A Honda generator might be on the horizon!
