You may find one or two spots during the week with hook-up if you are lucky. The last few years we have only had electricity one night of the week. There will be water fill and dump places at every overnight town. We ration the water and usually just fill and dump in the middle of the week. Hopefully it will not be very hot but usually there are a lot of generators running till about 9:00 and some all night long. We have not checked the towns out yet but since they are mainly small, I think the chance of any hookups will be gone by now if there were any to reserve. Sleeping in an RV is still way better than a tent especially when you have to leave in a pouring down rain in the morning. We are lucky that my dad is healthy enough to still want to do Ragbrai and drive the motor home. He usually just parks it in the next town and rides back one town or two and then back to get 20 or 30 miles in. Very happy to have him do this in his upper 70’s. He seems to enjoy it also.
