You’re positive a 110 has enough room, yes? They really are surprisingly small on the inside. Compared with a proper van they have miniscule load spaces, even LWB models. Lots of drive train and long wheel travel means high floors and big wheel arch intrusions.
That aside, I’d be tempted to advise you against it for the theft reason alone – it WILL be the target of theft, either attempted or (more likely) successful. Gangs of people specifically target these and few are recovered. And they can be opened with just about anything that fits in the door locks (soggy lolly sticks included), so useless for storing tools/kit in.
They’re great fun as toys – I’ve had two and I love them to bits, but as a practical vehicle they’re hardly sensible unless you really need the upper limits of its abilities – ie heavy towing or the off road ability.
