We're getting the van ready for longer trips, and I wanted to find a way to level the van more easily. We can get it close enough for comfort without a level, but we have found the propane frig works much better when it is closer to level.
Currently we use a phone app with the phone sitting on top of the kitchen counter. The problem is I can't see the readout from the driver's seat. Sometimes mrs. dhally uses an empty soda can on the countertop. Either way, there is a data communications gap with these methods.
So I found a device called RV Level and it works pretty well. It is a printed circuit mounted in a plastic enclosure and uses USB for power. Then a phone app to monitor level via bluetooth.
Here's the unit - it has LED's and can be used without bluetooth as well.
Here is my "electrical panel" to house the RV Level and an outlet to power it. I also added a voltmeter for fun. The outlets can be used for other things when camping.
The RV Level works pretty well, although I need to re-initialize the bluetooth every time I use it. It's also a challenge to calibrate it. I levelled up the van using a carpenter level on the floor to get the initial calibration. The nice thing about the app is it shows how many inches of levelling block I need at each corner, so I only have to do the blocks once.
The voltmeter is fairly useless, as expected.
