Welcome to the forum Graemelee
It sounds like you are going to have a lot of fun, (hopefully a whale of a time) and with a bit of luck and a little more free time coming to you both fairly soon, (and some decent weather) things are set fair for you both.
Yes you are spot on, things have moved on in the caravan world over the last 20 years or so, but it's a little like riding a bike.... you never forget!
Some of the more modern vans (last 20 years or so) are wonderful compared with yesteryear, and push button heating, running water, (hot and cold) plastic double glazing, multi burner stoves with integral ovens/grills, not to mention the fridge and all the rest are a far cry from the old Primus stoves, damp cloths (for cooling) and kettle for warm water, that many of us grew up with.
Why... even with my old van (nearly 20 years old now) its got a loo that is flushed at the push of a button, with an electric motor doing all the "hard work" .... I have no idea what caravan designers/manufacturers are thinking when they go to the trouble of specifying an electric motor, switch gear, and it's attendant wiring. fuses etc., and all the rest, to reduce the "drudgery" of flushing it manually! Unless a caravanner or guests are suffering from physical problems that make the task difficult, it seems to be going to a lot of expense and trouble to fit something that often is just not needed anyway!
( paws now dons his tin helmet and awaits the flak from all quarters!)
We are members of the CC (Caravan Club) and use their sites 2 or 3 times a year only, but find there are plenty of other sites, catering for practically every sort of taste and some of these are quite inexpensive and have good clean facilities. As always its horses for courses.
There's lots of very knowledgeable folks ( there's some who are actually quite nice as well ! :lol: ) on the forum here, and many are more than happy to give guidance from their own experience, knowledge of caravanning or their business/professional/educational experiences, so don't hesitate to ask if you need any information.
Don't be put off either by asking "simple" questions... in my experience they are often quite good ones!
As always regards to all and
Happy Caravanning
