Yea, don't get drunk and fall in your own campfire.
But that hasn't changed over the years.
Seriously though Del I have done a lot of offroad dirtbike and ATV camping when the kids were into the whole thing, so if you want to talk about it or ask questions I can probably help some.
I have also been around a ton of RV people.
To have AC you will HAVE to have a generator of decent output (2500 or better recommended)
There are some really nice quiet ones out there like the Honda portables, but they are not up to an AC unit unless it's a small window type (which can be great in something small)
Problem is the darn things cost more than 3x what that camper alone costs.
Without an AC unit you better stay in area's below 90 or so in the daytime, because not being able to get away from hot and sweaty sucks.
Heating isn't that big of a deal because there are quite a few good options there.
You will want to use 6v deep cycle batteries to make up your 12v RV system because they have WAY more amp draw time than 12v's (Even the deep cycle 12's)
On average 2 deep sixes will last 4x longer than the 2 deep 12's, and just about longer than four deep 12's.
Two deep 6's would give you lighting and radio or such for a weekend with power to spare and not need the generator.
I had 4 6v deep cycles in my motorhome and I could run multiple lights, water pump, stereo and the kids Xbox for a weekend without ever firing the generator up.
You will also want an inverter of at least 1500 watt.
A 1500 will run 110v hand held power tools, lights and small appliances, but a 2500 watt would be great.
A 1500 will barely run a coffee machine if it doesn't trip and shut down. (it will however run a hotel room style coffee maker just fine.)
A decent mat to put down outside your door to keep your feet out of any possible dirt or weeds is nice to have while sitting outside in your chair with a cold one.
It's even much nicer than asphalt or concrete even if it's clean and dry.
I don't know exactly what kind of "camping" you plan on doing, but some states and places will sometimes ban ANY open flame like BBQ's camp stoves or gas lighting outside.
In these places the inverter is nice for lighting and music out of doors.
Basic medical supplies, like band aids, wraps, pads and antibiotic cream.
Aspirin, Iodine, and hydrogen peroxide are welcome additions.
Sun screen, as well as hand and body lotion are almost a must.
A way to call for help is a smart thing. (cellphones are a little sketchy in a lot of places so a CB radio is almost better in case of emergencies (another thing your inverter can run if needed)
Solar panels to help keep batteries up in case of extended stays in what we call "Dry camping" area's where there is no utilities of any kind. (why use gas in the generator when the sun can do it for you)
I'll think of more things, but these are just a few of the things I have learned that make up some of the basics, and can make your camping life a lot more enjoyable.
All of the above applies to any RV, Class A to tent trailer.
