Browing around again .... I think a Luton will be my next project

Those nice square flat sides will be perfect for a conversion, together with the high roof means space galore compared to a panel van.
I really liked the idea of a luton with a tail lift that could double up as a patio space, but decided now that would not be a good use of weight if going for a van under 3.5t (which I think would be best to widen the market for both initial selection and resale), so now the Lowloader Luton is the favourite (so the rear-wheel base vehicle is not an option for a lowloader).
This fella looks pretty.
The Sevel vans are already the widest, and this luton body is a few cm wider and looks nicely integrated.
I don't think it would be that hard at all be make it look like a motorhome exterior with swoops and decals if that is what you wanted to do.
I use my underbed garage in my LT a lot and want some kind of garage area in a new conversion. The way the lowloaders are setup made me think could keep the original roller door and have a tall, but not too deep garage, super-accessible from the rear for all the bits and pieces you need and an internal partition
This is the interior space - I think it should be fairly simple to cut through the bulkhead to either make an access, or even bring the cab area into the rear box. Depends on the build layout really.
I noticed when looking at various van builds at Camp Quirky that putting storage across the cab seats is very common. I can see the benefit in having extra storage and counter space but closing off that extra space and losing it when camped is a definate downside.
