Points of interest route planner app? Any ideas?

I got this mail in from a reader who’s planning a camper van trip across the UK. He’s got an app enquiry:

My family and I are taking a road trip around the UK before heading overseas and I’m trying to find a route planner that includes Points of Interest and Camp Sites (for a camper van). I have found lots of route planners but nothing that contains everything inside one app. Are you aware of anything that does it all in one? I have the AA route planner and there a whole heap of apps that show campsites but I’m struggling to find a single source of info for everything.

Any ideas?

Right then what do you reckon? Is all-in-one too much to ask for?
