Geof, have you purchased the truck yet for your conversion. I am a new member to this blog site and could recommend a few changes. I am the Volvo Trucks salesman that specializes in RV/Motorcoach chassi specs. I currently work with 14 of the nations top manufacturers in the RV industry. The original pricing of a VNL780 is incorrect and the cost difference between new and used is not that significant. Feel free to send me and e-mail at

Good Luck
