Get set up fast with Wheel Masters RV levels that are easy to read at a glance. Choose models that mount with screws or adhesive for 5th wheels or travel trailers, with options that are sealed so you don't add fluid and brackets available for pin box installs.
Yes, it can be read from the rearview mirror. Mount it where you have a clear line of sight from the driver's seat. Good lighting and your eyesight will make it easier to read while backing into a site.
No. The vial is sealed and does not allow adding or removing fluid. If the bubble looks odd, verify the unit is mounted level and secure before assuming a problem.
Yes, adhesive mounting is an option. Folks use double-sided foam tape, Velcro, or an adhesive like Liquid Nails. If the back is open, filling it with epoxy can create a flat surface for Velcro. Clean the surface well and press firmly. If it's out in the weather, plan to check adhesion over time.
No, not when installed with the trailer completely level. They're designed to hold up to movement, shock, and vibration, with sturdy aluminum construction. Set the trailer level during install, center the bubble, and you should not need to readjust.
Drilling into a 1/4" thick steel pin box can be tough—use sharp bits and cutting oil. A 3/16" pilot was snug; stepping up to 13/64" made the bolt fit better, and adding washers gave more support. If mounting to a trailer wall, screws around 1-3/16" were noted; use a compatible RV sealant around fasteners to help prevent leaks. Make sure the camper is level first.
