The leveling gear that matches the kind of low you actually have

Leveling has two different purchases, and most roundups pretend they are one. You need a way to know how far off you are, and you need a way to lift the low support. A Bluetooth puck does the first. Blocks or a curved leveler do the second. Buying only the puck leaves the rig exactly as crooked as you found it.

Side-to-side is a tire problem on a trailer. Front-to-rear is usually the tongue jack or the landing gear, not another stack of blocks under the hitch coupler. Do the side that keeps the refrigerator floor honest first, then bring the nose up. The calculator on this site turns a degree reading and a track width into inches, and it will tell you when the number is past the point where stacking is a good idea.

How to choose

• If the bubble is off left to right and both low-side tires can roll onto a ramp, start with an Andersen pair. The 3604 listing stops at 4 inches. Past that, move.
• If you need pads under a jack, or you want one product that also builds a ramp, get the Camco 10-pack. Each nested block adds an inch, per Camco.
• If you are tired of walking back to a bubble you can't see from the tire, add a level sensor. Mount it square to the floor. Ignore any sentence that says it auto-levels the RV.
