Ideally I would have liked the next sized van up but I like the smaller vans because of parking, eventually I will have more Hydramaster ranking in it to utilise storage.
Daryl a SWB semi high roof transit will hold a Boxxer 421 or a 318 fine as I had a 421 in a SWB low roof, but I would recommend a 150ft hose reel to give it more space inide.
Doug the van is a Fiat Ducato 300, it's IMO it's more powerful than my transit (T280, 100bhp) and it's slightly taller 8" and a tad wider.
