In the UK alone, there are currently around 800 000 campervans and caravans. So the market is not that small.
But there are several categories of "special clients" next to campers that may be served with some addtional features. I think of trucks, busses and coaches, ...
Too some extend MRA is already catering with options such as "avoid toll roads, avoid highways ... Extra options such as "avoid city centres, avoid tiny mountain roads ... " may be better than a develoment for one specific user category.
in addtion, and partly for the same purpose, I would like to see a function that puts a flag every x00 km along the route that I am preparing which would help cutting a one-week trip in pieces. Which brings me to the scheduled POI update. It would be brilliant, for electrical car owners, to have the charging stations on MRA
