I'm sorry I can't recommend a particular Aire on your route, but there's a website which gives information about all campsites within 10 kilometres of the popular routes through France - here: http://users.pandora.be/leo.huybrechts/camp1.htm. Most people would advise you, especially as first-timers to find an overnight campsite, and most French towns have a very cheap municipal.
There are lots of people who would say 'DON'T ever stay overnight on an Aire' and those, like me, who would say 'We've done it at least twice every year for 27 years, and never ever had a problem'. If you're going to stay overnight on an Aire then choose a well-lit, full service area, with other caravanners around, and take sensible precautions.
It's amazing the number of 'tales' there are around of people who know someone who knows someone who was 'robbed of everything they had'. There are so many hiding places in a caravan that anyone robbed of anything of value must be negligent! We put all our stuff away in places that even your nearest and dearest might have trouble finding it! Our caravan has a million hidey-holes, all of which are inaccessible to a thief! However, I'm prepared to acknowledge that in some areas French police advice against overnight stays on autoroute services, and there are some with notices advising against it. In that case it would only be sensible to heed this advice, hence my first paragraph - find a campsite if you possibly can.
