Moochdockers are usually welcome over the holidays. However, it's a good idea to know the rules of good moochdocking conduct.
Don't assume it's okay to show up with your rig and camp out. Instead, ask your hosts if it's okay to bring your RV.
Helping out with chores like cooking, babysitting, dog walking, or snow shoveling will make you an easy guest who will be welcome back next year.
If you're staying with friends or family, they'll appreciate an offer to help contribute to their electric bill for the time you are hooked up.
Try to keep your stuff contained in your RV as much as possible. Don't put bags of trash outside the RV for animals to potentially get into.
Remember that Cousin Eddie scene in Christmas Vacation? Don't be that guy. Arrive with empty tanks, and if they get full, take them to a dump station to empty.
In some cases, you can hook up to city water when you moochdock. If temperatures are below 32º F (0º C), you'll need a heated water hose for this.
It's always a good idea to use a surge protector to protect your RV's electrical system, just in case the power supply is wired wrong or the power isn't steady.
