Borrowed a friends last year and it was fine. Everybody tends to get out of the way. This was 6.7 metres iirc.
Mpg’s were very low 20’s.
If we had the money spare, I’d have one myself.
I think mine is 6.7m and and not just country roads, I have had it through narrow medival french villages etc.
It is LHD which is counter-intuitive, means in the UK I can get over right to the last inch to squeeze by other traffic.
Biggest problem is actually that it is over 3M tall so you have to think in 3D – so overhanging trees and even sign posts, and that narrow/low brick railway arch quite near Cannock was an OMG moment. Handles like a canal barge, esp. in the draft from lorries.MPG is low 20’s if I am lucky.
I am selling mine now the little people are too big for the bunks, which is really sad because I absolutely love it.
