I am struggling to put this into words, but here goes...
Is it worth the money? Well for what it is, no. For what we want, yes.
I think it has a lot to do with what a buyer wants and whether or not there are cheaper alternatives. Also it would have a lot to do with how many times a year it will be used and whether you intend to sell it after a few years.
If you don't use it all that often then something cheaper may get you by, and if you intend to sell it after a few years then something that tends to hold it's value may be a better option.
For me there was no other alternative for what I wanted, the design of the GT is not found in any other CT as far as I am aware. Even with the top of the line GT, it still didn't have some things we wanted, so it cost us more to have those options included.
I am restricted as far as choice goes, therefore I am forced to pay what the manufacturer wants for it. I could have chosen a different design and probably a cheaper CT but then I would not have been 100% happy. The CT would more than likely not get as much use as a result and therefore would have been a waste of money.
By paying the extra, we end up with something that we are 100% happy with. It will get used on a very regular basis, because we all love camping. It is not something that I intend to sell so the resale value/depreciation is of no concern.
At the end of the day, it's not how much you pay for something, it's how much enjoyment you get from it. You only live once and you can't take your money with you.
