I'm trying to convince my other half a Goldstream Windup (equilivant to Flamingo) is the go, sadly she wants a caravan.
I, like you, prefer the Hawk type lay out, we have 3 kids and it is nice to keep them away from the kitchen when trying to do something in it, we hired an eagle once and did not like it for this reason.
There is a Goldstream for sale in Brsibane west on Caravansales now for 21,500. I like this one due to the large solar panels, 12 volt compressor fridge, and awnings etc. For me, a 12 volt fridge is much better then 3 - way, although 1,000 folk will happily argue this.
The net has lots of details of Jayco's getting into all sorts of remote locations, and home again, I think it is the way they did it is why they made it home. So with some good dust and water proffing, such as posative pressure vent system, you'll easily do it with sensible driving.
Another thing I like about the Goldstream is no need for Dumbo Mirrors when behind the 105 series, they are more narrow then Jayco's.
Good luck with the search.
