Even on a Sunday? I think it's only a little way on the Periphique...
If you like the M25, you'll LOVE Paris. Avoid it, unless you're adicted to stop, start, ad infinitum. PARTICULARLY on Sunday evenings after a warm weekend. Any daytime is a no-no really. Dead of night is no problem. Make sure you have a really good navigator and a decent map.
The N138 Alencon - Rouen road isn't much fun (although no lorries on a Sunday), but there is another route - 3 hours LM - Rouen leaving LM bang on 1600 Sunday (you won't do that with the van, but not far off it).
I'll be off line for 2 to 3 days, so Ill PM you the route.
