Hi, firstly congratulations. I also await delivery and, as is perhaps quite understandable bearing in mind it's an expensive long term purchase, had one of those questioning moments not long after signing the order.
In my experience, that soon went away and you won't be able to resist dipping in to the forum and planning how you will use your camper. Although I have a few months to wait I now have nothing but a real urge to get out and about in it. IMO the benefits will far exceed the costs.
We are all different but I would wager that in a few weeks, once you get the commitment into perspective, you will be itching to get delivery. Good luck.
