Sat Nav Help

Not sure if this is the right "room".

Hi Folks, I know this has probably been asked before. We are going on our first trip abroad with the van next month (Spain). I'm looking for a Sat Nav app for my tablet to use in Europe. I don't mind if it's free or paying for it as long as it's good. It
would be good if you could set it for caravans or trucks, to avoid narrow roads etc. And should be able to use offline, and be able to search for specific places i.e. c'van sites. Am I asking too much? What Sat Nave apps do you guys use? What do people think
is the best one. Many thanks.
