Just think about it for second.
Roto Grip based in Utah.
Storm based in Utah.
Both in the same building.
If they(Roto) has a production issue they can get it corrected on site.
No phone calls.
Why would Roto get there stuff from a different vendor?
?
Dyno and Track were both based in Texas(before mergers) so that seems to follow my logic.
--------------------
If it doesn't have DT or RG stamped on it.
Just leave it in the bag.
