I'm a big fan of the Tvan but some of the reasons you just mentioned are the reasons I just cannot get myself over the line, yet.
Buying a new camper can be very personal, what is a must for some is a what ever for others.
Look at some like: All Australian owned.
Complete Camp-site Exodus 11 or now named RVR.
It's and big wide world of options out there catering for every market..
You need to write down a list in order of what are the most important to the least important things, so when comparing 1 apple to another apple
your list can help determine what fits best.
We'd start with a few key points.
How quick to set the awning........ Not just the camper.
Outside living area, and what is shaded or covered from rain and bad weather.
Kitchen Alot are just cheap and very crap lay outs. Can you access everything freely specially once you have started cooking.
Ball weight, some will surprise you.
Water storage. is a must for us as we love showers.
Shower!/Loo set up. does the shower wall go all the way to ground. Does it have a roof, youd be surprised on how boody cold a hot shower becomes with only a thin Cavan wall with no bottom and specially no roof.
I can go on for hours but I'll stop here.
