The replacement inner lift tube BD84FR has recently gone inactive and is no longer available from Bulldog. With this I recommend replacing your landing gear with the Ultra-Fab Deluxe Electric Landing Gear Set # UF17-943010. I prefer this over a typical landing gear set as each jack has its own motor connected directly to the jack. This allows you to raise and lower each jack individually. view full answer...
Hey Tim, thanks for reaching out!
The Stromberg Carlson Base Pad Extreme for RVs and Trailers # SC33VR have a 6,000 lb rating for each Base Pad Extreme so you're looking at a total of 36,000 lbs for this kit of 6. Ideally your jacks will have the weight distributed evenly among the jacks so there won't be any problems with too much weight on 1 individual Base Pad.
Unless you'll be placing a LOT of load on one Base Pad, you'll have a hard time overloading them with your setup. view full answer...
