There are city/county parks scattered around the country, and some of these provide free parking and electrical hookups.
Casinos are another potential place that may offer electrical hookups. These businesses want to draw people in, so they offer great deals to travelers.
There are some fairgrounds and sporting arena parking lots that have accommodations for RVers. These locations almost always have massive parking lots, and they include designated spaces for RVs. Sometimes that includes a few hookups!
If you want to plug in your RV at your own house, you may want to consider installing a 30-amp or 50-amp plug so you can easily connect everything.
