I'll put it this way...
For many years people drove without seatbelts, most of them are alive today, never had an issue.
For a long time cars didn't have ABS or airbags, most people who drove those cars are fine today.
Cars didn't have crumple zones, tow ratings were a recommendation, and WDH with sway control was unheard of.
People all the time like to use the argument "we never had those safety things in my day and I'm fine". That's because every person who isn't fine, is dead from the lack of safety equipment.
Its an additional safety measure, something you may not ever need, just like a seat belt. You may ride around for your whole life unbelted and be fine.
I'm a paramedic, and trust me when I say this, seeing just one dead kid face down in a ditch after being ejected from a vehicle because he was not restrained with a seatbelt... Makes you a believer in seatbelts. For every story that you have about " I know a guy who was thrown out of a car and would have died if he wasn't", I have 100 stories of people who would have been alive with just a headache if they were belted.
Point being, even with a large truck, its a modern safety tool and can help avoid trouble.
