Hey Jeannette,,
Oooo exciting for you,,
Can’t comment on the Habitation model side, But The Nest is on a Boxer 320 Chassis & I have found it Fine, I would suggest having a good look at the Earth point & the Battery Trey (Bot of which are on the Drivers side Wheel Arch area) as it attracts water & therefore Rust on mine, Also look at where the cab meets the Habitation on the Chassis.
Good luck, & hope it’s what you want
Do you know the dimensions, Jeanette? It looks quite compact.
