Greetings and welcome from another past colony.... Canada that is.
I have seen the Jaycos (Australian made) you speak of on a trip to your part of the world, very nice indeed and very different than models sold in North America. RVs here are much bigger and heavier. But then again gas (petrol
) prices here are very, very low
compared to yours, and tow vehicles are not as large.
if you're considering an American made unit, you must be careful with a few things: mains (electric) is 110V not 220V and the entry door(s) would be on the wrong side for down under..., I believe as well that propane connectors are differents. There may be other differences, so caution is the word.
Looking forward to see your pics.
