Driving motorhome though France to Spain

TE, there's lots of response to your previous thread. Does that help?

TE,  Overnight stays were covered in your previous enquiry.  Fuel is available at every supermarket In every sizeable village when you are off the motorway, but you will  need a selection of bank cards for the automated pumps when the attendant is not there.  Have a safe journey 

The route I use from Bordeaux to Jaca with an 8 metre long motorhome to avoid the A63 tolls is via Langon, Pau and the Somport tunnel. I recorded details of my last use of this route on Polarsteps and you can read it >here<.  I find it more convenient and interesting than traveling down the A63 and crossing the border at Irun. There are some narrow sections on the ascent road to the Somport Tunnel but visibility of oncoming traffic (HGVs use this route) is good and these sections can easily be negotiated. There is a video of the route on my web site >here<.  Once through the tunnel the Spanish roads to Jaca, Zaragosa, Valencia and beyond are wide and fast.

Have a safe trip
