I researched the subject of a suitable motorhome for my requirements in my last couple of years in full time employment. All the shows were visited and I bought MMM regularly to narrow down what I wanted/needed in the way of facilities and extras.
Fortunately, I seem to have got it right first time and am totally happy with my motorhome. The mileage is 20,000 and the vehicle doesn't 'miss a beat'.
So in answer to the question, I shall not be buying a new motorhome and suspect my first shall be my last !
