Here's some more that come up on here quite frequently, that I haven't seen anybody mention yet:
I'm better because I paid cash for my RV and get to live debt free. Nooo, I'm better, because I know how to use other people's money wisely, to have the things that I want while I'm still young enough to enjoy them.
I'm better because I never drive faster than 60mph with my RV, making me much safer because I can stop quicker. Nooo, I'm better, because I keep up with traffic (even if its going 70mph) and don't risk causing a traffic slowdown.
I'm better because I carry Emergency Roadside service (Good Sam ERS, AAA, whatever). Noooo, I'm better, because I'm resoureful enough to take care of my own problems without such, and don't have to spend $$ on roadside service plans.
I'm better because I carry a spare tire for my RV and am prepared to handle a flat tire on my own. Noooo, I'm better, because I rely on roadside service to take care of that, and don't have to waste $$ and space on my RV for a spare that will probably never be used.
The OP is exactly right - Threads/discusssions on here end up like this waaaaaay too often. In some cases it does take away from the intended purpose of forums like this.
