Just for clarity, when you order a BCP a TB in usually included, unless otherwise requested. My addition of that option is just to show one example of an RMK with a "lot" of options. Not all were chargeable, in this particular case.
You can order "TB" on a lot of models @ a $30.00 charge. Model #3, #4, #5 & #7 for example, although a "BCP" option is not german to this option...on these models.
Hope this helps, Capt. Chris
