i had a jayco eagle, was stolen and I'm just about to buy a new jayco flamingo outback.
they are not the toughest van around but if you look after them they will last, they are comfortable, well featured and supported wife and I and two rough nut boys very well.
we did a lot of extended long range trips with the eagle and it never missed a beat, didn't notice on the back of the car and they are not heavy so fuel economy was good as is storage capacity and beds are comfy. being self sufficient, battery lasted us around 10 days mainly lighting, gas fridge/some cooking lasted about a week with one 8.5 kg bottle (I had a sep bottle for the webber & i did have two bottles on the van)
id have no hesitation in recommending one but I would say if your planning off road trips like the birdsville, oodnadatta where you have long klm's of corrugations, it will suffer, my father in law borrowed mine, took it to birdsville and it took a bit of a toll.. draws/cupboards etc never fitted as snug as they use to and, it won't take anything serious. very weatherproof.
for info too.. we have a webber Q2 so all our cooking was outside apart from boiling water or some toast in the grill which meant we didn't have much issue with keeping the kitchen clean and the van smell free. If you get a 'road' model and simply want a bit of extra clearance jayco can lift them for about $200 though its simply a lift..
id say you can probably get a good 2005 eagle for around $15 privately but you won't get that through a dealer. Consider too, brand new eagle $21 ..if u can get a few bucks more, go a newy..
if your in melbourne and want to go the new way, PM me, id be happy to refer you to good dealer..
bang for your buck, i don't think you can go wrong..
