Is 20 amp service enough?

YES but not all at once
You should be able to run ONE air conditioner OR the electric water heater OR the Micowave OR a hair dryer OR one space heater OR an Two of the following electric skillet or A single burner (Induction or resistive) and a coffee pot.

The Ands are the Kitchen counter top stuff other than the microwave

Done it.

OH. I forgot the TV, Modern TV's do not draw enough power to count. so yes you can run the TV in addition to the above.

Footnotes: Dogbone adapter to make your unit plug into 20 amps. if necessary a pair of 'em (50-30-15) (Kind of how I did it)

If you need a long cord 12ga cords can be found at most Home Improvement stores as well as Sears and K-Mart. those last two have a 12 volt cord, 12ga with a push button on the outlet.. I really like that push button, it gripps the plug plugged into it so it's less likely to come loose.

Camped for years at our county fair that only had 20 amp service. HW heater on propane and never run microwave and AC at the same time. BUT...as others have said there system is probably old and no longer up to code. I would make sure to have some type of EMS in place. Lost my converter and microwave due to loose lugs on there connectors at their power posts.

Had to do it for years when in construction camps. often only 15a . still do when camping in a friends property or on genny boondocking.
Power management becomes your mindset, use propane for fridge, furnace, cold water heater. use only one elec. hungry device at a time. A/C - or toaster-or hair dryer or coffee, etc. Then take the experience home to lessen your demand charges from your electric co.

One at a time on large draw items, tv is low current draw. Large draw items toaster, coffee pot, A/C, hair dryer, water heater, microwave.

High draw items can only be used one at a time on a 20 amp circuit. These include, but are not limited to:
1. Converter (only when batteries are low)
2. Microwave
3. Water heater
4. Refrigerator
5. Air Conditioner

In an old campground, with only 20A, the whole system will likely be old. It's not the same as plugging into a new 20A outlet with everything at full power. I would run what I could on propane, and only use the AC or MW, if you can verify continuous good power. The important thing is to have enough power to keep batteries charged.

Heck, even the 30A receptacles can be worn & loose. I use a 50A to 30A adapter if I have a 50A service on the ped.

Who’d want to camp without AC, TV and microwave?
My goodness next you’d be talkin’ about internot.
