Hello Again Fred
I see in your second piece you wrote
.....& why a dandy?,
If that was in response to my question then my point wasn't clear.
I was asking "Why a Dart?" The Darts are about 4' across folded plus wheels. Deltas are about 4'10" plus wheels (Some bespoke Darts and Deltas have the wheels inboard) Now the next size up the Designer or Discovery (Same Size interior different) might be at or above your width requirements at 188cm. (Wheels inboard) Being short though they avoid the snaking issues of longer trailer tents. The extra width does make a big difference to the living space.
Your spending a lot of money, go through ebay, gumtree etc and go look at ones close to you so you can visualise the different sizes. If your near the North West go to Riva and have a browse. Any questions you find while looking there you would be sure of an honest and authoritative answer.
All Dandies are within the 750Kg license restriction for post 1997 licences.(the big Destiny one only just) I don't know if you have such a license or an older one where you can theoretically have a unit of up to 8.25 tonnes. Whichever you have I hate to see someones options limited by trepidation. Have you thought of a couple of B+E driving lessons?
1...2....3....4.....5 Right now you have counted to five none of that was meant in a Sid the sexist way giving Fred a hard time because we now know Fred is a Freda. No it may well be that you have talents or confidence you never would have believed. You don't need the licence so just a couple of lessons might fire you up. Conversely the Caravaning Club do courses on towing. I know you don't have the space for a caravan, but if the course is the right price why not? People have lot's of misconceptions about trailers. i.e. most non towers wouldn't understand, trailers get harder to reverse the shorter they get.
If any of that seems a little grumpy it's not meant to be. Everyone would love to see you in a Dandy and preferably the right one for you.
