Reminds me of back in the day. I hate helmets. I used to wear shorts and nikes when out riding my atv's. Heck, a shirt was optional. I knew other guys that would come with helmet, goggles, roost protector, gloves and boots, even when it was 100 degrees. I dressed for the ride. They dressed for the wreck. It's a wonder I'm not dead, and looking back....it's hard to say they were wrong.
You might get away towing heavy with a half ton. I got away with that too, for years and years. But it's still hard for me to say the other guys are wrong.
Now one of my F150's is 4800 lbs. My F250 is 7200 lbs. With a large travel trailer behind you, which do you think is going to handle the load better when it hits the fan? I think that's what drives most of these guys. They're simply dressing for the wreck, not for the ideal situation.
