Im using 100lb sliders for the 2 drawers and the camp stove drawer. Purchased at Lowes, $20 each. I will try these out first. My drawers pull out full length, i cant imagine more then 100 lbs not being enough. My Dometic frige is mounted on its own full slider made for the fridge.
I can always upgrade if i need to later. 100lbs is the strongest Lowes carried.
