Caddy is much bigger outside and about same inside, maybe smaller if it has a bulkhead.

Also worth noting. A lot of modern small vans, and the Caddy is one fall outside the GVW greater than 2000kgs.

These vans carry reduced speed limits on single and dual carriageways. 50mph for a single and 60 for a dual.

Pain in the fucking hole if you're looking a decent small van that you're never going to load up to the balls.
