Chausson 640 Motorhome

Hello all Chausson 640 owners.  We are currently selling our caravan and wishing to go back to a motorhome.  The Chausson 640 is the one we think will suit us best.   This is a long shot, but hoping some lovely folk out there will be able to help us out.  We need to see if the motorhome will actually fit down our drive before we commit to either used or order new.  We appreciate the measurements are available, but our drive has a slope and you come in at an odd angle then once past the pinch point it opens up to a double garage.    We are hoping (and naturally we will reimburse any outlay plus any extra if required) that someone would offer to come to our bungalow and see if it fits down our drive.   I have been to sellers to see if they will pass on our info to current owners, still waiting, but not overly hopeful.   I have tried local hire companies, but to no avail.,  any they did have are to far away, i.e. Hampshire and we are in East Yorkshire area.   I would love to hear from anyone that would be willing to help us out.   Fingers crossed.  Kathryn & John
