Stromberg Base Pad Extreme improves stability of your parked and leveled RV. Boasting a muted slate gray color that blends in better than competitor’s pads and a lower profile to fit under smaller units as well as units with a higher clearance, you won’t be disappointed! 6000 lbs capacity, 3500 lbs when two are stacked. Side panel finger hole for ease of carrying and retrieving. No magnet that falls out – unlike competitors. Dimensions: 10” across top, 12” across bottom, 7” tall, or 12-3/8” stacked. Can be used with 1” or 2” thick Base Pads on soft surfaces – like hot asphalt or sand. Lightweight poly-carbonate materials – like bulletproof glass. Available in 1, 2, 4 and 6-packs. Made in the USA!
