Mike,
A VERY nice addition to the P -15 rail is to go to the hardware store and
buy a package of that split foam tubing that is for wrapping around hot
water heater pipes for insulation. Put that around the rails and make it
fast with some nice matching colored vinyl tape. Reason....after a while
that rail gets mighty hard on your back and really hurts after a while.
The padding is quite cheap and can make a BIG difference in comfort.
