I have a 2020 Xplore 304. If by issues you mean manufacturing problems then no more than you'll get with any other caravan.
If in terms of usage, well for just the two of us it works very well. We have a porch awning which is mostly used as storage space - good for hanging wet coats, boots etc, and storing foldup chairs and tables. We have an inner tent for it which I did sleep in on a camp bed when our grandson and daughter came away with us, but they have their own tent now.
The supposedly 4 birth design is marketing blurb at its best. Certainly three adults could sleep in there and the bunk bed would support a very small child. But the overall space is too small to spend any length of time in it - this is where the awning comes in handy again. The 'dining area' is very useful for the two of us and at a push we can get 3 adults + grandson around it by using a small stool as an extra seat.
The kitchen area is compact and not a lot of spare work surface but the table in the awning comes in useful again. Three gas burners are ok but like most they're a little close together - but that depends on what your using to cook with. Sink - well its a sink. There's a little folding extension to the work surface that gives a little more space and is useful. Two 230v sockets nearby.
The 'lounge' end has a fold down shelf supposedly for a TV or whatever. It has a 6kg weight limit. A 230v socket plus 12v socket and TV antenna outlet are nearby. We don't have a TV but just use the shelf for the kettle, teapot and cups.
Overhead lockers are good for storage but there's not much under seat space. The L shape 'lounge' we find is good but there's no room under those seats for storage other than a small draw and cupboard for slippers or similar. The 'dining end' has two underseat storage spaces. We can get one mattress topper in one and pillows in the other. The other mattress topper sits on a seat when traveling but on site, once the bed goes away they're stored in the awning.
We took the mattress for the fold down bunk bed out as well as the fold up sides and we use that space to store the duvet. That works for us very well. It just folds up out of the way. The main bed is fairly easy to put up but suffered from the same problems as we've had in others vehicles. The end supports are too far apart and the first time I knelt on it it made some ominous sounds as if it was going to break. I added some strengthening at the ends and also made a middle support leg.
There's a single bed at the 'dining area' end.
The bathroom is small to say the least but once you get used to it, its ok. We can shower in it and I'm about 98kg and 185cm tall. Takes some practise. The shower water tended to leak out the door despite the curtain but some foam insulation tape cured this - mostly.
It tows extremely well - we have a Qashqai 1.5dCi and at times I forget its there and have to watch the speed.
If you have any other question just ask away.
