Polarising poles apart batman.
We had a Finch for around 10 years. Never used safety poles, never had a roof catastrophe. Use em' if ya like, I can't see an issue with peace of mind. If I was supplied with them when we purchased the camper, I'd a probably used em', occasionally.
I'd not be to critical on Jayco supplying the safety poles. The decision to do so may more than likely be insurance based, duty of care and all. But hey, as I said whats wrong with a little piece of mind. I lock the campsite up nightly (regardless of were we're camping); kayaks, surfboards, fishing gear and other items with a penchant for "walking" all get put away or secured with various cables etc. Helps me sleep, not to mention waking to find all my toys intact and ready for action.
Great little rant on setting up the camper there Prodigyrf. We had a similar military style of bivouac activity on arrival. With a couple of variations:
I always removed the plastic cover from the door before attachment. Never had any dramas with it.
Our other variation had the levelling and leg winding completed as part of the initial setting up.
That was the one aspect of your setup that I didn't much like; you didn't level out the camper (fore and aft), and set the stabiliser legs down prior to entering and setting up the beds. In my mind thats a recipe for disaster. A bit too much weight in the back and the whole unit can go arse over apex. Sure its never happened to you, but I've seen it happen (to an old couple in a caravan). Now whilst the whole prospect of seeing a camper or caravan with its drawbar pointing to the sky and a couple of codgers flailing about inside, does have some comedic merit. The funny side of the argument would fail to seen by those in the throws of shock and panic.
Apart from that, yeah pretty quick to set up. We could often be done in under ten minutes if the planets aligned. They are a clever little camper.
