Welcome @Wazza from another Perthite!!!!! Nah not really knowledgable... we just "wing it"
Lots of options to go for. I'll start with a few and others will add to it:
Extended drawbar
Extra 12 and 240V powerpoints where you think you'll need them
2 x gas outlets if they'll do it
If you lived nearby @Crusty181 I'd say a diesel heater (Ongoing joke!!!!)
Maybe do an introduction post and ask the question on there. That way you'll get replies on your own post making it easier to follow?
