Hi Allan,
We have a 2018 Compact and just love it.
It has a tare of 2100 and can go up to 2750.
We do have a 3 way fridge so cannot comment on off grid time - we tend to spend most of our time off grid.
We have a 100L water and 60L fresh water tank - we do have a grey water tank as we like to go to national parks etc and a lot more places now ask for them.
We have an Aussie Traveller lightweight annexe - it is easy to put on / pull down. Easily stores under the bed and a great annexe.
Sorry I cannot comment on current price range but give Paul at the yard a call and he will be able to answer all your questions - we found him very helpful when we were looking.
Hope this helps,
Tony & Irene
