The host of the Runaway Roses had carried a basic bottle jack in the truck for years and never really liked it. After trying the Power Mountain Tallboy, that old jack is getting retired. This really is the bottle jack you did not know you wanted or needed, but you probably do if you tow, haul, or go off-road.
The jack shown in the video at the end of this post is the Power Mountain Tallboy, a dedicated off-road bottle jack. It comes in 2-ton, 6-ton, and 12-ton versions so owners can match it to their rig. The one featured is the 6-ton model, which fits heavy trucks, travel trailers, and toy haulers.
The first big difference is the steel base plate. Traditional bottle jacks sit on a tiny footprint that sinks into dirt or gravel. The Tallboy has a wide steel base that spreads the load, so it stays stable on soft ground, gravel pads, or uneven sites. It works fine on concrete, too, but it really shines off-pavement.
Power Mountain includes a heavy-duty plastic case that is easy to use. The jack and all the parts actually fit back in without a wrestling match. Inside, foam inserts and Velcro straps hold the attachments so they do not rattle around in the bed of the truck or RV storage bay.
Attachments make it versatile
The Tallboy kit comes with several smart attachments that solve real-world problems.
- Flat plate for frames and crossmembers—There is a flat plate that sits on top of the jack or extension. It works well on a flat trailer frame, a truck frame rail, or any other flat lifting point.
- Axle cradle for safer lifts—The axle cradle is shaped like a shallow U. It lets an axle tube sit down into the attachment instead of perching on a small round jack head. That adds grip and feels far safer when lifting a rear axle to change a tire.
- Height extensions for tall rigs—Two different extensions come with the jack. A short piece adds roughly 3 inches of height. A longer extension adjusts with a pin, so the user can set it where needed. This is handy for taller trucks with 37- or 40-inch tires, where the axle sits much higher than stock.
- Support sleeve under the screw—A metal sleeve slides under the threaded screw portion of the jack. The user unscrews the jack top, drops the sleeve in, then reinserts the screw. The collars on the extensions slide over that sleeve for extra support and strength when extensions are stacked.
- Handle and setup—The handle comes in sections that snap together. A fitting at the bottom tightens to lock it as a solid pumping handle. To add height, the user unscrews the jack top, installs the sleeve, chooses an extension, pins it if needed, and then adds the flat plate or axle cradle.
Lift range and capacity
With no extensions, the 6-ton Tallboy starts at about 8.5 inches of height. With all the extensions in play, it can reach roughly 37.75 inches. That range covers low trailer frames, lifted trucks, and off-camber situations where extra reach helps. The 6-ton rating equals 12,000 pounds, which is close to the full weight of many heavy pickups.
To show it in use, the host jacked up the front of their travel trailer. The frame is a square channel, so they used the jack with the short extension and the flat plate against the flat frame bottom. It lifted smoothly, felt stable, and let them pull the front block out with ease.
The jack also went under a Ram 3500 dually. After chocking the wheels, the host placed the axle cradle under one side of the rear axle. Pumping the handle lifted the truck until the tire hung in the air. The axle sat securely in the cradle, and the wide base kept things steady. No extra extensions were needed for that lift.
Between the big base plate and the axle cradle, this setup feels much safer than a skinny bottle jack or a wobbly scissor jack. Bottle jacks are already very strong, and these add stability and better contact points. For many owners, it also beats hauling a full-size floor jack in the truck.
The Tallboy suits a wide range of rigs. The 2-ton model works for smaller vehicles. The 6-ton model, shown here, fits most three-quarter-ton and one-ton trucks plus many RV setups. The 12-ton model, rated at 24,000 pounds, is aimed at very heavy applications.
Final thoughts
For anyone running an RV, truck camper, trailer, or off-road rig, the Tallboy looks like a smart upgrade from a standard bottle jack. It packs strong lifting power, real off-road stability, and thoughtful attachments into one compact kit. The host of Runaway Roses now keeps it in the truck for travel days and trail days, and it is hard to go back to the old setup after seeing how well this one works.

If the only advantage of this over regular bottle jacks is the base plate or extensions, then simply put the bottle jack on whatever pads one uses under leveling jacks, or large pieces of wood one takes along for the front jacking point of the trailer. I’ve done both.
I was going to say the same thing. Save your money for a cold brew, or two.
