We just returned from our 5-day family trip, and it was wonderful. This was my first time driving a motorhome (also my first time driving in the UK). But Benny was so easy to drive. It was a breeze. Also, it was smaller on the outside than what I saw in the videos and bigger on the inside (as a living environment), with plenty of room for a family of 4.
Also, Shaun was great in explaining all the bits and pieces of running the motorhome very elaborately. For first-timers, there were a couple of things that I feared doing, like driving a motorhome, emptying the toilet cassette and such, but none of them was an issue at all. So, I encourage you to try doing it. Cotswold Motorhome is going to be our choice for our future holidays.
