Beech Lane Wireless RV Leveling System, Made in the USA, User-Friendly Phone App With Real-Time Precise Leveling Measurements, Advanced Wireless Camper Leveler, Included AA Batteries, Patent Pending

After years of relying on the bubbles that Camping World installed...They were wrong!!! Whoever installed the pitch bubble (on the side), must have just eyeballed it, because when I installed this new system, you have to check your level, which I did on floor inside door with an actual level, turns out the tongue of the trailer was almost 2 inches LOW when bubble on side showed level.Installation is a snap, hardest part was measuring distance between axle and tongue jack, and distance between outer edges of trailer tires. I decided to mount the transmitter on the wall of my wet bay, which is the furthest rear compartment on outside of trailer, passenger side. Distance between there and my driver's seat of pickup is at least 30 feet, with several walls for signal to go through. NO PROBLEM. I decided on this compartment, because the leveler has a temperature sensor that shows readout in the app! Now I can monitor that wet bay and make sure it stays above freezing during late or early season trip when I'm not winterized. I compared the temp reading with a known calibrated reference, and the temp sensor is right on the money.It's really nice to see exactly how level your rig is right from looking at phone app in the driver's seat, makes it easy to move trailer to that sweet spot where you might not even need to level it, not having to yell back and forth to wife "is it good???" And if it's off, since you enter those measurements I mentioned, it Is able to calculate to the fraction of an inch, how much you need to raise/lower, which is displayed in a very intuitive display. So I know if my Anderson leveling wedge is enough to level the trailer by itself, or needs something under it.Although I didn't need customer service for this product, I can tell you that Beech Lane customer service is GREAT, from my experience with three of their fridge fan products I also have. Yeah, guess I'm a Beech Lane fanboy now!

This device is a delight... fine-grained data, easy to use, and intuitive. Also, huge thanks to the designer, who helpfully answered a couple of geeky questions... A+ support (the unit was fine; my question was about a tricky application).If you're in a situation where you have a rig that is sitting crooked and you don't have a good way to establish an initial level reference, all is not lost. Use a long bubble level on some nearby surface with suitable shims, calibrate the Beech Lane unit to that in both axes (eyeball as best you can, as there are no orthogonal square edges), then go tape it to a visually promising surface. You can also use free sensors/physics apps on most smartphones to give accurate roll/pitch/yaw data, and this can be used to get a good idea of whether said surface is more or less an accurate 90 degrees from the floor in both axes.All this might sound geeky and complicated at first, but it's painless and easy to tweak if you don't get it quite perfect the first time. The goal is to have the app believe that it has been referenced to a level rig. At this point, you can start playing with moving things around (for us, that part was tricky with a very non-flat gravel pad, but we also had the Beech Lane curved leveler kit to make short work of the crowned edge.Here's where you can start iterating to get it perfect. Once the app is showing that you are close, set the brake and do a little reality check with the level (or phone) on the floor or whatever you are using as a reference. When you find that you have it nailed, you can re-establish zero reference on the sensor without going through it all again, and if you wish, shoot in the two screws to keep it right where you put it and be ready to use it for all future parking jobs.But you don't have to attach it permanently... it is a great general purpose leveling tool, and in our case we have a couple of mobile lab trailers that could use a little tweak when I get motivated to hook up and do battle again (but the RV was WAY off, and urgent). I think of this in the same category as digital multimeters, laser thermometers, infrared camerasm and all those other tricorder-gizmos that help you see physical phenomena that are hard to assess by eye.All in all, this is a great product. If I were to make any suggestion, it would be to add a jig that brings out 90° edges so it can be tucked against a ceiling or wall to help visualize "square"... even though that is sometimes marginal in an RV and is not really necessary since you can calibrate it to any position.Incidentally, if you have trim issues on a boat from the unbalanced moments of tankage, batteries, and other heavy objects, it is basically the same problem. You can use this sensor to accurately observe relative roll and pitch while moving things around to get her on her lines. Feedback via the app is very fast, and it is easy to use.

I purchased this because it was very time consuming to level my camper using my trusty level. A lot of times I have to set up by myself (wife still works!) and having to place the level, guesstimate how much I need to raise the low side, pull onto the leveler, (I use the red ones), get out and check the level, get back in the truck, move the camper a bit, get back out and check again, and repeat ad nauseum until I am leveled side to side. Then after disconnecting the camper from the vehicle, place the level in the door frame to level front to back. This requires numerous trips from the tongue jack to the door until the camper is leveled. Whew! Lots of steps and time is required. I set up our camper a couple of weekends ago and once it was leveled the old-fashioned way I installed the Beechlane Leveling system. The instructions were clear and easy to follow. Installing the app was a breeze and worked perfectly. One suggestion for anyone purchasing this product is to have a 25' tape measure available. Reason being is you have to input a couple of measurements particular to your camper.This product is simple, effective, and I would recommend this to everyone who still relies on a manual level. My only regret is waiting so long before purchasing it.
