Yep same argument I have with my self regarding replacing our camp trailer....
I get talking to yourself, but arguing requires replies which seem to be troubling in several aspects.
We could just refer to all this as justification for big boy toys. I bought a boat two years ago, it hasn't moved yet. Last year, I bought a Roadman Camper, a motorcycle tent trailer, had to build a custom hitch for my Trike and its still not on yet. Oh, 4 years ago I bought an Army Hospital Surgical Tent, very heavy stuff, about 14X24', I laid it out when I bought it, rolled it up and it has never moved since then. Can't justify any of this stuff, except I just have it.
I'm sure next summer many here will buy new(er) toys, prices will drop and desire increases.
Whatever you decide to do most likely there will always be a cheaper alternative that you didn't take.
