Camp Lakewood is our go to place when we visit my mother in Effingham, IL. It is a well maintained park that is completely gravel and the sites are level. It is next to Lake Pauline which makes for a picturesque setting. It is close to Wal Mart and other shopping and restaurants. The park is heavily wooded and we always need to ask for a special site where our satellite will work. They only have a few. It has recently changed hands, but the new managers appear to want to continue to make it a great place to stay. Rates are around $40 per night and they have cable and typical camp wifi.
There are a few long term residents, but their rv's are well maintained. I would rate the camp as above average and recommend it as a stop if traveling I 70 or I 57 through Effingham.
