Have a T5 and love it, going away on Saturday for our 4th trip this year, rain not a problem
It does cost to keep it roadworthy and have annual habitation check (gas, electrics etc). It's cheeper than hotels but more exensive than a caravan
We keep coats, Wellies, breakfast stuff and sleeping bags in it all season then all you need is a change of clothes and you're off.
Quick to set up when you arrive, journey easier than towing. We have a base second 4 person tent that we throw out the door ( or a really simple 2 man pop up if it's just a night) and put things in there so that day trips are easy, you just put the roof down, turn iff the gas and drive off.
We don't often get electric hook up, we wild camp or stay on cheeper pitches, most things run off gas and the battery lasts over a week
We used to have a detachable awning but found it made day trips much harder as you have to line up carefully to reattach it. That's why we got pop up tents. We decided it was cheeper to get a Flamina wind out awning that pay for a divorce. Sadly we argued like mad over reattaching the awning tent.
The joys are wonderful and you also have fab cheep days out as you can make your own coffee and lunch
Can you tell I'm a fan
