Also view the Sunseeker 2350LE . Fiberglass front cap and roof.
Built on the Ford E450 super duty chassis at 14,500# GVWR. (Has a lot of storage and 4400#'s of payload)
Its a non slide unit with a U-shaped dinette table that spins and locks in place to offer more room while sitting as well as working in the kitchen. The corner bed is a real queen 60x80 on a Serta upgraded mattress.
I would also look at which water heater is offered. Be careful when choosing tankless models , the Girards don't appeal to me when boondocking. I prefer the old fashion Atwood gas/elec model.
