Hello Jason. It sounds like you are not going to bother, but just so you know that this is the right decision...
I brought over a Left Hand Drive campervan from England thinking that it would be easier to re-register than a RHD model, and, of course, because it's France, it wasn't!
It would have made a difference if I had had a certificate of conformity from the manufacturer I bought it from, but, unfortunately, this wasn't possible.They are a small van conversion company unknown across Europe - even though they are extremely well known in England.
The process took months and there was a lot of expense, but, as I speak fluent French, I managed. During the process I showed the paperwork to my French friends and they even found it difficult to understand. Also, as someone else has said on here, getting insurance for this type of vehicle is not straight forward!
So, I personally advise that you don't import any van conversions from the UK. If you are looking to save money then ready-built well-known brands of motorhome (e.g. Hymer) are easier to get re-registered, but I would suggest you consider other comments on here about the safety aspects.
