First roll of ribbed silver grey carpet arrived today, very impressed as it matches the Murvi cabinets perfectly. I’ve no need for stretch carpet on the build and it saves me re wrapping all the cabinets from the scrap van. Only £7.50 sqm so actually pretty cheap too.

Nice and cosy now, started a little of the first fix too.

Finally got the cab lining down and more deadmat, dodo liner and used the last of the 25mm fleece. Had to use 50mm for side walls. Running low on liner, will also have to top up on 50mm fleece for the bottom half.
Now I’ve got to re-engineer the cab lining so I can put a shelf above it for bedding storage. Enough for one day…..

Another hard day on the roof, I’ve refitted after much modification, the ply skin. A lot of measuring and re measuring and still got a few bits out, nothing that won’t be dressed when carpeted and fitted out. I really hope I can get all this sorted soon as it’s very uncomfortable work, my neck is still cock-eyed!
Re used the Sprinter strip lights too, I liked the flush finish and quite expensive to replace with equivalent new ones.
Still got an eye on first fix electrics but not started yet, just leaving provision. Going to loop a main circuit, H&C water and the kitchen 12v over the back door, will be accessible later on if need be.

Steadily chipping away at stuff, started the first fix today, tomorrow I’ve got 3 days off so will complete the cab area fit out. New DAB FM aerial fitted to replace OEM which was leaking, split FM to the cab ICE as DAB useless on the move, digital feed sent to rear head unit with 12v amp feed.
Reinforce cab roof tray tomorrow, add USB/voltmeter socket, cut 5” holes for overhead cab speakers, built a locker wall for it and adding 5” crossover speakers for rear ICE.
Awaiting speakers and head units, NOS Pioneer SPH10BT @£50 up front and Kenwood DAB 7200 double din @£110 for rear, so I can aux in sound from the TV, has built in Alexa too, gone for plainest looking speakers I could find and will colour match bezels to suit interior in grey.
Been a month or so on the build now, still working above gutter level!! One day soon I’ll start working below that line, probably empty the van out and do the floor next.
Opinions invited: I’m not sure whether to go for van floor liner or 25mm celotex/battens either way with 12mm ply. I can probably just about afford 50mm headroom loss, I’m looking to build this van as the Murvi Ducato was built, only light fixings needed to attach interior to the floor.
There will be two freestanding minibus (integrally) belted mounted to the floor and wall with spacers and appropriate strengthening bars, and I’ll be adding drop vents for two gas lockers, propex gas heater and leisure battery vents.
I’m more than happy with my Dodomat for the walls and roof but thinking celotex might help me keep a level floor to build from.
Downgrading the inverter link but will retain the modified sine for heater and hot water, add a pure sine for tv & laptop, though I’m fitting as much as possible to run on 12v eg TV, multiple USB sockets. Off grid use will be minimal but adding it for occasional trips.
Thoughts also invited for a smart battery charger for hook up use, remembering I’ve 200W solar already on the roof.

Trial fit of over cab tray, carpet went in nicely, slightly sagged but will straighten that out when the wall is added. Solid hinged flap will assist noise control and improve speaker performance..

Went to the Caravan Show at the NEC just to crib some ideas but it was simply too rammed and we left after 90 mins… did manage to poke around the latest Murvi and aside from a different (IMO worse) layout in the WC the design was unchanged from my 1992 breaker.
Surprised to see the electrics like this though - on carpeted wall - and not especially tidy, I’d have though a bit of heat shrink would look better than yellow crimps. New furniture is also very bulky.
Glad we went as it’s confirmed we are building it best for what we want.

Fitted the ex-Ducato wall cabinets today, I’ve run out of carpet (well a piece big enough for this!) but they’re up and rock solid. Stripped off all the old carpet first, cleaned out the insides and left the carpet lining in, sprayed it with clear lacquer just to give it that new smell!
Fitted electric heater over cab to heat and cool the rear. The van is feeling a bit smaller now!
I’m going to leave the existing floor down as it really is a hard job to remove it and it is a very good installation, just means I’m going to have to compromise on insulation, though I’ll add what Celotex I can under all the cabinets, there will only be about 2-3sqm of actual floor area.

New stereo finally arrived this morning, Pioneer SPH-10BT. This is the single din unit that has a really solid phone mount built in, clumsy app to set it up but once done it’s fit and forget. Handy for sounds and Waze, new 3-way 5” roof speakers combined with co axial 4” replacements on dash sound plenty good enough. The soundproofing is also helping, though I haven’t done the cab doors yet.
Have a double din for the living area to install later on with 5” component speakers, all FLI ones which are pretty cheap and perfectly acceptable, and I’ve sprayed the bezels and grilles to match the grey lining.
Might seem a bit OTT or wrong priority but it makes for a bit of music in the build, and after 3 T4s in which I couldn’t hear the radio at all on the motorway, it was a must do job!

Struck lucky today - investigated the flooring, after stripping out the entire bay behind the axle I found I’ve got top quality bus floor-treaded ply fitted, was riveted at 600mm centres. It’s in one huge piece so I sliced across the axle with my multi tool, lifted it up and the steel floor is almost perfect. Removed the mild steel structure that was around the wall/sill, it was unpainted and one piece just on the turn. Lifted the bitumen felt up and all is good.
Staying with one source, I nipped over to Deadening.co.uk and picked up their floor liner.
Too cold to do anything today so all prepped for tomorrow, will put the heater on first thing so the van warms up.
Most of the brown you see is glue, dust and sawdust, a couple of tiny areas to AquaSteel better, but ready to lay on. Doing the job in 3rds so I don’t have to risk snapping the floor.

A bit more done, it seems I have a surplus of deadmat so added more where suitable. Bit chilly today so ceased the wall trimming, will do that once the other 2/3 are done. The Lino was a pig to get up put it’s all out now.
I’ve decided - as there is little chance of finding a walk through set up from the cab - to add an insulated half bulkhead behind the front seats, this will make it even more cocooned in the living area.
The living area will now be fully encapsulated with deadening and insulation, and the cab will be much more cosy on the move - we’ve planned for piecemeal parts of the NC500 this year!

Looking like a really nice build so far :)

Thanks a lot for sharing the photo's, seeing how other people do this stuff is so much help when your a complete newbie like my-self

Tip run yesterday, also fetched the sofa/bed bases from the shed and tore the carpet off them. Suddenly I’ve got a temporary excess of space… Bilt Hamper rustproofing kit arrived today so I can fill the sills and door bottoms from inside then get on with the trimming.
Lucky break no.3 there is a good 12v take off under the drivers seat, 10mm cable now ordered to attach the split charger to, all the first fix coming along, found some decent trunking to run over the back doors to the kitchen.
Final batch of DodoMat picked up on the way to work, total of £700+/- spent purely on insulation and matting - had to be done though and very effective, all the doors now shut “like a Golf”!
16sqm of carpet lining and a set of side steps arriving this week, gradually getting the big bits in and paid for.

Have you looked at other options instead of a split charger (old technology and not very efficient) ? You’ve spent £700 on insulation which sounds like you want a quality build, it seems a shame not to use a better means of charging the leisure batteries. Just a thought, don’t mean to offend in anyway.

Didn’t really think about any other options - I’ve got two LA batteries I’d rather use but please let me know what better job I could do? Have room inside the living area for everything, the only link between cab and camper is a battery cable, at the moment!

I’ve had a Google, I’m not sure what other tech there is available to charge on the move.. solar will do a fair chunk of the charging but obviously need better than that. I can build the van up whilst sorting out other options, not planning any trips for a while. Would I be better considering a battery upgrade at this point if it makes sense as a whole?
All advice gratefully received, I’ve had/built six vans over the years but not since all this new electrical tech came about!

Would this be the kind of thing? Looking at the spec my 10mm won’t be man enough - if I’m going B2B I’d be better upgrading to 16mm as the batteries will be just in front of the rear axle.
Alternative theories suggest if I have capable solar (200w) and generally use hookup, a split relay (I’ve used Durite as a rule) would be good enough. I could lay the 16mm anyway and use the 10mm elsewhere on the van just to futureproof it.
The massive outlay on insulation was really driven by fact it simply cannot be done (properly) at a later date.
