You will find LP gas at most all private parks and trucks stops. The COE and state parks will not have LP in most cases. You can download from the Flying-J a list of all fuel stops in USA and prices of pump gas, diesel, and LP. Parks that do not have a refill station will have a truck that comes around and takes care of this service.
Look down at bottom of all pages and you will see "Contact Us".
I have to disagree with some of this. Very few parks that I have been in offer propane service. None that I have been in, or worked in, have had a truck that comes to the park to take care of filling tanks. This may occur in huge RV resorts but not regular campgrounds.
We do offer it here but in Texas it requires one certification for tanks and one for motorhomes. Since we rarely have motorhomes coming in asking for refills (maybe 3 per year) it doesn't make sense for them to pay for me to get certified for that part. I do removable tanks gladly but can't do the ones mounted inside motorhomes.
