Hi Gliden07,
Each state has different camp amenities. The common ones are
1. No electric, no water and no sewer at the site but has a dump station and potable water at camp. In this case for a camper, you use flashlights or the on board battery and lights in the camper. The camper is self contained less Microwave and AC. We also nick name this boondocking or off the grid.
2. Electric, (120 vac shore power), no water, no sewer at the site. But has a dump station and potable water at camp for you to fill up. The electric comes in 15 amp, 30 amp and 50 amp are the most common. A 20 amp may be in there too. For your camper, a 30 amp will run everything in the camper, just not all at once.
3. Electric, (120 vac shore power), water at the site, no sewer at the site. But has a dump station and potable water at camp. The electric comes in 15 amp, 30 amp and 50 amp are the most common.
4. Electric, (120 vac shore power), water at the site, sewer hookup at the site. This is known as full hook up. But they normally still have a dump station and potable water. The electric comes in 15 amp, 30 amp and 50 amp are the most common.
We can go 4 full days with on board tanks if we stretch it. This means not adding extra water and not dumping until the 4th day. Now, it does take an adjustment to be able to do this, navy type showers, (turn water off between wetting and rinsing off), be thoughtful about doing dishes, only do once a day verses 3 times a day. (wipe them down and do full soap and water once a day or do dishes out on the pick-nick table in tubes and heat water on the stove). For the guy, walk to the camp rest room as needed to help cut down the toilet use.
When we boondocks in the Adirondacks we can go 9 days on a black tank. I do use a blue tote on gray water and I do add more fresh. And one time I had to do a partial black dump. I'm "into" camp chores, what ever they are. This way of camping can be extended with choirs as long as needed. We recharge the batteries off a generator. I have not gone solar yet.
Until I retire, we are mostly weekend warriors with extended trips in-between and can go the whole weekend easy (2 nights, 3 days) with on boards tanks. But like I said, you have to "think" about water usage. At home, the thought of running out is not as apparent and it is amazing how much we all use daily. If you do not adjust your ways, you will run out of on board tank supply on day 1...
Most of our camping is number 2 above. We have power but use on board tanks can a go to the dump station on the way out of camp. We are using the entire camper, AC unit, micro wave, shower, toilet etc. When we do get to a full hookup site, habit kicks in and we are still in water miser mode. However if we need to get out of camp quick at the end of the stay, full hookup can be a time saver, I'm dumping and rinsing while packing up
No matter how you camp, there are all good.
Hope this helps you find a state park near by.
