My Master is L3H2. This is van code for wheelbase [L1/L2/L3] and interior height. [H1/H2/H3] H3 gives me 50-60mm headroom, standing up straight. I’m 181cms tall. The floor is 26mm of ply + carpet.
I say Reno Master. It is in fact a Vauxhall [UK]/ Opel [EU] Movano but it’s a Renault Master with a Vauxhall badge on it. There is a third variation - the Nissan Interstar. Same animal. As far as I can tell, there are minor variations in what constitutes l/w/b amongst this tribe of vans.
L3 is long w/b but it does tend to vary amongst manufacturers. And then there’s l/w/b Jumbo - something approaching 2m of rear overhang.
A van doesn’t become a camper just because it has windows behind the cab - in UK, anyway. Others here will know the implications of that in FR. DVLA will only reclassify a van to a camper - should one want to - if they get photos showing various camper-type stuff installed - bed, table, cooking gear etc. The benefits are minor. Mine is still class 7 but the ferry companies see side windows, awning, decals - it’s a camper.
Bear in mind that the l/w/b vans I described, made by Renault, are 3.5 tonne gross vehicle weight. The VW you fancy is way smaller than that. The Renault equivalent is the Trafic/Nissan Intercity/Opel - Vauxhall Vivaro.
As for longevity, my Movano is 2004. It has done over 215k miles/346k kms, still pulls like a train, drives like a car. Amazing fuel consumption - I’ve done dozens of fill-to-fill checks and get between 33 and 38 mpg, depending on load and roads.
Charante is correct. A resident of any country cannot legally drive a vehicle registered in some other country. As a res of FR you will not be able to reg a vehicle to UK plates.
Well … it can be done if you arrange your paperwork to appear to still be reg as res in UK. The trouble would start if you were pulled by les flics and they discovered you were actually res in FR. A Brit driving licence is the only one I know of with an address on. My SP licence does not, because it’s good for all EU … as is a UK one. DVLA told me they have no instructions or intention to change that, post 01/01/2021.
However, a thread on this site has confirmed that it is not impossible to register a converted camper van in FR - just well-nigh impossible. The van in question a VW T? was converted by a specialist UK van convertion company and every scrap of paper to do with the convertion, financial and technical, was required to get the thing CT’d. I think one must ssume it’s impossible for a DIY converstion - sadly.
