Those are all fine units, if they meet your wants and needs. Pick the one that suits you best. But it sounds lke you already did!
Unfortunately, by putting a hold on it you really tipped your hand. I hope you negotiated a good price before you did that, cause it is usually very hard to bargain afterwards. You might want to call the dealer and say "Nice rig, but no thanks, I can't afford it". They know you want it, so they will try very hard to talk you back into the deal. Then you can hold out for a good price. I would set 20+ percent off the Winnebago MSRP as my target, but only you can decide when the deal is right for you. But remember, there are a lot of Winnebago dealers and you can buy the same model from each and every one of them. Tell that to the dealer as well.
