Plan the utilities so motorhomes can pull in forward to take advantage of the lake views.
As far as spacing...naturally, big is nice but you have to work with how much property you have.
If it's on a usable lake the lots will be occupied daily no matter what size they are.
There's a RV park in Pagosa Springs that is billed as 'resort' and very expensive. We've never been there and wouldn't want to, but the sites are always filled. Whenever we drive by we ask "Why". It's not the type of park for us but many seem to like it. We viewed it again a couple months ago on our way to a national forest campground ;) and our site was also on a stream. The RV park doesn't have much spacing between sites and there aren't many sites but the draw is it's bordering the river. However, the riverfront sites are back in so the front windows aren't even facing the river, they're facing the highway.
Have water the people will come. :)
