LCD TV for in Bigfoot 21RB

[GeorgeR]

I ordered Bigfoot 21RB trailer with the TV prep package. I would like to order LCD TV but don't know what size TV would fit. I don't want to:

• exceed the weight limit for the articulating arm mount
  
• have the TV sticking too far on the right. What is the distance between the center of the articulating arm mounting plate and the right edge of the cabinet?

I am aiming either for Sharp 19" LCD/DVD combo (12.5 lb.) on sale at BestBuy or Viewsonic 19" (9 lb.) on sale at Costco. They both are 19" wide.

Any help will be greatly appreciated.
George.
