Yes I did use the heavy duty brackets. More pricey but I figured it would be better in the long run. I also put a piece of wood and a piece of carpet under the bed but We are keeping about 1/4th for outside storage. I used the tv bracket and cabinet that came with the camper but I did install a tilt mount on top of it to be able to turn it down some. I am using the refrig storage area to store my Lawn chairs , alum table and Patio carpet, also planning to hang TV cable On hooks in this area. I also installed a 3rd set of manual jacks in front of the tires to help stop wobble ,I did the same thing to my last camper and seemed to help. I'm sorry about pictures but I'm new to this site and I'm not quite sure how to post them.
