Going to be getting a 5 ton this week, when I test drove the vehicle it was very obvious that the air brakes are very responsive. It has been overhauled by the military and had the ABS upgrade. That said since my sons will occasionally be operating it, I was thinking that a set of seatbelts might be wise to add in, but don't want to have to hack anything in. I did a quick search on the forum and didn't see any mention of a company that anyone has used for installing a set. Just that its been done by members in the past. Any recommendations on it. Thanks in advance.
