I installed a set of the MUD UK seat rails. Not sure if they fit a 110 but the vendor will. Ask Stuart or his son. His son invented them because he is about 6'5. I have the legs and arms of someone that is about 6'4 and they REALLY help me. Give about 2' of leg room..I think. Didn't measure. Just felt the difference...Up a little and back. Easy install! I have a D-90 though. Feel like I'm part of the truck now instead of a grasshopper on a pebble.
Not sure about change in design strength in case of an accident...But if I get hammered by another car that's probably the least of the safety concerns. Knock on wood.
