We also did the hire before you buy thing. We were originally tent campers, SWMBO hated it...
First hire was a Complete Campsite 16foot (older model) not too bad, but dark inside, and yes it rained almost the whole weekend. Admittedly, it was without LED lights and all the smart stuff available.
Next was to try a Jayco Swan Outback, but the hire mob did not have an annex, so we ended up taking their Expanda and loved it, just couldn't afford to buy one..
We then borrowed a 2004 Jayco Eagle Outback, without battery and free camped for a weekend, hooked up to the battery in my Prado.
We ended up with a Jayco Flamingo 2007 as my wife is a big fan of flat surfaces, like the hard floor, bench tops etc..
While we do like outside, cooking is done inside, for things like pasta, veges etc.. the meat is cooked outside on the Weber Q.
We love it...
FWIW, the guys we hired off seem to be closing their doors and selling their Jayco's on ebay, they have a Swan, Expanda and Sterling.
