Wow! Sounds good.
We're getting ours converted professionally so it's a good job, van bodies in Morecambe, but we spent a bit more on the van to get new model in a good condition/spec. That means half converted. We are getting more done than expected though. It'll have 4 beds but no kitchen or storage. Electrics for supply from hook up or from engine. Not up on terms, or forgotten them at least. Leisure battery, split system iirc with hookup. Heater for extending camping season.
The roof was an issue. Our money was tight to get the top roof makes of reimo and sca. The others hadn't developed a SWB Vivaro roof in the 2016+ Vivaro yet. Eventually our converter told us about drivelodge garage roofs. He'd not used them before but said they were as good as poptop and other second level companies. The other positive was that they have a spoiler instead of the rubber strip seal at the front. We had spoken to enough VW owners to learn that the rubber strip solution had more issues. Noise was one issue but one VW owner had nothing but problems with the strip coming off no matter what the converter did. A top VW converter too.
We'll probably end up having to get a load of extras not least a large water container for nights in the wilds. Seat covers for day to day use, new mats, silver blinds for the front windows, bike carrier options, etc. I'd like to fix roof bars for an open canoe we're talking about getting. If we don't it'll only get canal use (one is behind our house). I think the 40 or 50kg will just take a canoe and paddles suitable for the three of us and touring kit. I hope so because the van will be our only transport other than bikes or public transport.
Do you have any bike carrier recommendations? Either fiamma racks (bolt on or removable) or tow bar plus tow bar mounted carrier?? I am like towbar option personally, with a removable ball perhaps if not too expensive. We'll not tow anything I think. Do you have a carrier?
