I'm happy to report that we've done two trips (three nights in total) in the new motorhome and are getting to grips with the new way of doing things.
Biggest shock (which I had anticipated but didn't want to believe) is that the 120l onboard water tank doesn't last as long as a fully serviced pitch water supply


And, oddly, when I set the truma hot water to 'hot', it seemed to switch itself 'off' once it hit temperature, so I ended up with a cold shower (which had started hot but ran out just after the point of no return). Grr. It's exactly the same heating system as the caravan and that never happened?
However, that aside, on the plus side, we arrived in the dark on Friday night, reversed onto the pitch, and within 5 mins were fully operational. We'd travelled with a full water tank.
I no longer have to make our bed.. simply press a button and the incredibly comfy bed drops from the ceiling

. And our daughters share an over-the-cockpit big bed, so they're very, very happy. Especially as they have a TV to themselves....
On Sunday morning we cleared up from a hearty breakfast, closed all the cupboards, put the two shower bottles away, unplugged the electrics and off we went, to the beach for a dog walk before heading home. We would never have done that in the caravan.
It's a bit tighter on storage than the huge twin axle plus Land Rover Discovery boot, but we seemingly need to take less 'stuff' with us.
Assuming no lock-down, we're off again at the end of the week, four nights this time so we'll need to do a food shop at some point. That will be when we really realise the difference in outfits I guess. No more 'popping' to buy bread and milk.....
But a great start to our new holiday regime so far. I might even drive it soon, if Mr H hands over the keys....
