Welcome and enjoy the experience!!!
I’ll start by saying don’t constrain your search to location. There is a wide range of styles and quality out there, so take some time to look around to find what really works for you.
You may well find that the best match for the style and quality you want and crucially the budget you have to work with, means you may need to travel much further to find the ideal combination. I’m in Herts too, but ended up using a converter in Devon!
So take some time too look at options, how they compare (or don’t) and you’ll be able to make a much more informed decision. Given the inflated costs of base vehicles now and rising costs of everything, that’s more important now than ever.
And lastly, don’t be put off by long lead times to schedule in the work you want. Good converters will usually have a lengthy lead time and will be well worth the wait.
