I'm describing a very selective non-argument point of view which is becoming more apparent. Ah, here's a good example with the emphasis added...
Sorry; "I can't afford it" thus "it's stupid" isn't an argument.
What makes you think it's worth a few hundred bucks? Have you done research into the materials, construction, and operational cost of producing a RTT? I think you're a little off base.
A lot of times we think things are over priced because they're simply outside our means to afford them. Or we'd simply never pay that price. (I would never pay XYZ for X is pretty reasonable.) Mostly because we lack understanding of how much it truly costs to produce or what it's actual value to us may be.
Recently I had a friend staying with me to help me build a RTT rack and skid plates and bumper. He's a mechanical engineer and fabricator and I had no idea about the amount of time that went into just designing something properly. Talking 8hr days, measurements and designing in SolidWorks. The time spent getting steel, and actually fabricating. really changed my perspective on the prices of things. I had thought for some time a lot of the racks out there were obscenely over priced. Now I realize only a few are over priced, but most are probably not getting rich off the racks they sell and I was really wrong on that front.
That being said, I highly doubt that a RTT is worth a few hundred bucks. Especially since aluminum panels which most have would be a few hundred bucks for just the floor.
Using space on your roof rack is a better argument. You should stick to that complaint.
Or a better argument from the price standpoint is that you just don't feel the return on investment is worth the initial cost for you. That'd be reasonable. Some just don't see it worth paying the price just sleep on a flat surface with a mattress. They feel they can get the same reward with a ground tent and cot for example. That's a valid point I feel.
Everyone's "was it worth the investment" is a little different. And we all tend to like what we have. Thus we tend to rationalize our decisions to ourselves and others.
