I wish there was a way for me to find out if the modifications I've made to my snoozer seat work.
I put a locking clip on the seatbelt, this allowed me to pull the seatbelt much tighter across the carseat and it can't change length
Robot Check
And I made a new tether using heavy duty carabiner clips and paracord
I also keep it on the middle seat.
My biggest fear is the car rolling...
