I was told A/C could not be used, and friends who have stayed by the lake warned it was a single receptacle. Still, I paid for electric, I hoped I could at least make coffee.87 volts when it first cycled, 94 by the time I took the pic, then rolled up my power cordI guess we will run the fridge on propane, limit our battery use. I plugged Mr Coffee directly into the pole. Better a $2000 coffee pot..inverters are expensive.I guess I can re-hook to the truck for a daily "recharge".[img][/img]

A surge protector alone won't do you any good in a scenario like this ... what you want is a full feature EMS that can detect a variety of power source errors, including high and low voltage, in this case the latter. So ... what's the point of your post? :hFWIW, your situation is exactly why I installed a 1000 watt PSW inverter - not for planned dry camping (which we do little very little) but for those emergency times when we lose campground power for one reason or another but would still like to have limited use of 120 vac to power a toaster, or coffee machine, couple of fans, etc. I've wired the inverter output to dedicated receptacles in the camper and because my trailer is protected with a Progressive Industries WMS-HW30C I can leave the trailer's main service cable plugged into the campsite power post and allow it to continuously monitor the power source and decide when / if it's safe to turn back on again. No surge protector alone will do that. ;)

Or, just monitor voltage yourself.In any case, you are correct to NOT use their power unless it is 108 VAC or higher.The exception may be your converter (read its voltage range in its owners manual) and any resistive appliances like water heater.

If I hook up to somewhere with only 50 amp service (with 50 to 30 adapter), would my EMS be adequate/safe?

Your 30 amp EMS will work just fine.The reason being that your 50 amp male > 30 amp female dogbone adapter is wired to pick up ground, neutral, and just one hot leg from that 50 amp power source ... so when your trailer or EMS is plugged into the 30 amp end of the dogbone it's exactly the same as plugging into a 30 amp campsite source.

FWIW, your situation is exactly why I installed a 1000 watt PSW inverter - not for planned dry camping (which we do little very little) but for those emergency times when we lose campground power for one reason or another but would still like to have limited use of 120 vac to power a toaster, or coffee machine, couple of fans, etc. I've wired the inverter output to dedicated receptacles in the camper and because my trailer is protected with a Progressive Industries WMS-HW30C I can leave the trailer's main service cable plugged into the campsite power post and allow it to continuously monitor the power source and decide when / if it's safe to turn back on again.
