The Bluetooth signal range is very good. I can can easily connect with the device from my car. I mounted it in the pass thru storage area, but it seems like it could mount inside the RV easily. The instructions via the app are very easy to follow. Calibration was a snap. It was fun watching the pitch change while un hitching the RV. It shows you how much the RV is off do you can plan leveling blocks strategy.

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.

Installed in my Artic Fox PU camper and install was super easy. Got it connected to the app and got the initial level set. After that drove around my yard and worked like a charm, giving me the offsets, brought back into garage and was back to level. Great product.

The Beech Lane Wireless RV Leveling System is a fantastic product that has made leveling my camper so much easier! Gone are the days of hopping in and out of the vehicle multiple times to check a manual level while trying to back onto leveling blocks. With this system, I can monitor everything in real time and get my camper perfectly level in no time.The setup is straightforward, and the wireless functionality works like a charm. It's accurate, reliable, and a total game-changer for anyone who dreads the leveling process.The only downside is the lack of an on/off switch. Without one, the AA batteries will drain over time if you don’t remove them after use. It’s a small inconvenience for an otherwise excellent product, but adding a switch would make this absolutely perfect.Overall, highly recommended for RVers looking to make their setup quicker and less stressful! 🌟🌟🌟🌟

Traveling and I just arrived at my RV site. Without any doubt, the Beech Lane Lever is the most useful leveler I have used!! I had two other brands ($$$) prior to finding and installing the Beech Lane Leveling System ($$). Compared to this unit, they were total trash, a waste of money, hard to use and unreliable.Beech Lane is the BOMB!!! 👍🏼👍🏼I’ve had the Beech Lane Leveling System for two years and never had an issue when pulling in to level the RV. What used to be a two person job is now, easily, a one person set up. No more communicating with a second person looking at the bubble level attached to the RV, or jumping in and out of the truck to check it.Without reservation, the Beech Lane Leveling System is the most reliable RV leveler I have ownedTwo years installed and the original batteries are at 37%! Pretty darn good 👍🏼

This is worth every penny! Once I leveled my trailer and mounted this, life is easier. I like it so much I bought another as a gift. Easy to use. Once the app is installed and you have the leveling calibrated, you just open the app right before you start parking your trailer and watch your phone. I use cantilever blocks to level and setting the trailer couldn't be easier. I also used it to check if I had too much weight on one side instead of evenly distributed. Highly recommend.
