If it is not more than 7.5 ton then it can be driven on a grandfather rights licence . The conversion to camper (motorcaravan) makes no difference from a driving licence pov . The class 4 has no relevance to the licence it is purely for the type of MOT , and applies to any motorcaravan even over 7.5 tonne my 12 tonne RV was a class 4 mot .There are some very interesting ideas there terry! Apologies for the late reply my email is receiving no notifications what so ever I only came on to write a reply and ask a question and noticed there were several more comments!
I’ve seen a Mercedes 814 bus for sale, apparently it comes in at 7.5t. The seller told me if you convert it to a camper/motor home it’s class can be changed to a “class 4” and it can be driven on a standard car licence?
I can’t find any info to substantiate this, the only reference I can find is to do with grandfather rights driving up to 7.5t.
Also regarding the caravan, it really isn’t an option for me at this moment in time. I’d like to not have to rely on camp sites etc, understandably whatever we end up with won’t be at all “stealthy” but I want something a little more portable and I just feel a caravan limits your options!
Class 1 and a heavier vehicle may end up being the only Option!
