1. Motorhome Seat Belts are tested to make sure they meet DOT standards. I know this because over the years, we have had to add modifications where, after additional testing, the Seat belt/Shoulder mounts did not meet standards. The OEM sent the modification kits for us to install.
2. LAP belts behind the Driver/Pass cockpit area also have to meet DOT standards for mount. We have also had over the years, to install additional mount kits on some motorhomes that after additional testing the Lap bolts were not secure enough or met DOT standards.
3. IF the Motorhome does NOT have Lap belts in certain seating areas of the motorhome, we will not add any extra belts and the OEM will not approve extra belts other than what they provided as they are only approved and tested for that specific application.
4. As an Aside, I was a scout leader for the years my son was a Boy Scout. The BSA will NOT allow any Scouts to be transported on an official BSA outing unless all occupants are belted. This meant, I could only transport Scouts that I had seat belts for in the Motorhome. AND, the Scouts had to be secured to the belts.
5. Securing a child that requires a Child seat is a problem in a Class A and Class C motorhome. IMO, the lap belts and the direction of the couch or seats is not correct for safely securing the child seat. The securing seat anchor should be facing forward and NOT sideways, which eliminates a lot of RV's from securing a child seat correctly.
6. Texas requires ALL occupants to be secured. I have never heard of what happens in a Motorhome with Children. I do not believe anyone in Texas has received a citation for transporting Children or even adults NOT using the rear belts with the Drivers and Passenger seat's occupied by someone already. Cops have better things to do than pull over motorhomes to check for this. BUT, have a BAD accident and people are injured or die, then I will bet the Lawyers come out of the woodwork against the OWNER of the RV. Doug
