Best of luck with your search. We were in the same boat as you a couple of years ago quite capable of doing the job ourselves but I knew the finish wouldn’t have been quite what I wanted and we were only doing it once so we opted to have one converted. After me finally convincing the hubby it was what was going to change our lives. Which I can honestly say it has, its amazing.
We found a small 2 man operation near where we live after looking at and visiting 12 other places.
I personally wanted to spec it out to exactly what I wanted roof type, bed choice, colours, accessories, worktop material, blinds not curtains the choices were endless and the only thing stopping me with our converters Nigel and Mark from Kicking Kampers was space and my imagination.
They did a phenomenal job, we brought a van pre registered with 7 miles that took a chunk off the price to begin with and obviously from that your converters have a set price and deviations cost from that. We ended up with a unit much cheaper than a vw manufactured unit with far more accessories and functionality and haven’t looked back since.
My main advice would be to look at as many vans as you can before you start your build as the options are mind blowing. Our personal choice for a smaller converter rather than the larger quicker ones was just for the personal touch, we got pictures at ever stage, we could go see it any time we liked, they explained everything so thoroughly we felt part of the build without even needing to pick up a screwdriver. An amazing experience and I can honestly say we haven’t had a fault with any part of the van and love it. However not so lucky with driveaways but that’s a separate thread.
Happy hunting and Happy travelling. I wish you the best of luck and I’m kind of jealous, as the whole choice although might seem daunting, with so many options was one of my favourite parts of owning our 1st VW child.
