Sun Company Lev-o-gage II - RV Levels (2-Pack) - Made in USA | Leveling System for RV, Camper, or Pop Up Trailer | High Visibility Ball Level (No Bubble)

Nice item, look and size.

They work as intended. Easy to install once you know its level.

Added these to our travel trailer on the back and passenger sides. I use them as quick reference points and this allows my wife who spots me backing up to gauge how much leveling we need to do before I get out of the vehicle. Quick sticky applications on the back. Easy to work with. No bubble so shouldn't freeze in winter storage. These do help out but I would still verify with another method prior to fully disconnecting. I have noticed at time the passenger side one says were are level front to back but the bubble gauge tells us we are off a little. Very minor differences but are noticeable enough to warrant a second verification method. Overall would recommend for a quick reference for the spotter. Might save you time and stress with those more uneven sites out there.

Simple, rugged, easily readable, "nothing to go wrong". It's not a precision inclinometer but that should be obvious. It's in the stone age "crude but effective" category. .......I'm designing wheelchairs and scooters and need to know what grade the hills are. Installed this on my scooter handlebar and now I have a quick answer to the question. It also serves an accelerometer, once you understand its dynamics. The engineers probably tried to achieve critical damping but the physical characteristics of the system can't be reduced to a simple second order solvable problem so they did the best they could with the design. As others have reported, the ball does often exhibit a little bit of stiction. Not really a problem as long as you understand what's happening. If you're on a moving platform measuring grade (such as what I'm doing) slope should be measured both uphill and downhill then take the average to cancel offset errors. If you're on a stationary platform such as leveling an RV, make sure you have the thing installed precisely horizontal using a real bubble level, and always tap the thing when taking a reading.

I love these because they are large and easy to see, even in the rear-view. I chose this one precisely because of the ball used instead of a bubble. It is easier to see and won't break up like bubbles can and become inaccurate. I put one on drivers side front of my RV and I can see it in my rear-view well enough to level side-to-side without ever getting out. Front to back is handled with tongue jack. They are stick on, but I also use a silicone caulk (same I use for sealing the RV) around the top to also help to keep it adhered. Not sure if it is needed, but also keeps water off the factory adhesive strip. I'd recommend these to anyone with an RV.

Update 8/8/24: I've increased my rating from 1 star to 3 stars. The increase is due to exceptional customer support. Today, I received an unsolicited message from the seller saying the following, "We sincerely apologize for any inconvenience regarding your order and would like to offer you a full refund for your purchase." They did this proactively as a result of my review, which I was not expecting. I really appreciate a company that stands behind their products. Original review: I'm honestly not sure why people like these so much. Perhaps I got a dud, but I see other reviews saying the same thing as me. I mean, it looks cool, but I don't find the sensitivity or precision to be nearly as good as a traditional bubble level. I attached both this and a bubble level on a horse trailer, and the lev-o-gage consistently took quite a bit more of an elevation change for it to register any change, versus the bubble level, which moves anytime there was even a small change in elevation. The video shows about an 8" change in elevation of the hitch (significantly off level), but there was no noticeable change in the lev-o-gage, as compared to the bubble level. I even tried tapping on it, but it still didn't move. I find myself fully relying on the bubble level rather than the lev-o-gage.

I have a teardrop trailer with a kitchen on the back and I always had to use the kitchen counter to make sure it was level. This meant constantly walking from the front to the back, over and over again. I attached one of these to the front center and the other to the front side so I can see if it's level without having to walk away from the tongue jack.

Good price, double sided tape was provided and adequate. Does the job and is easy to read

Installed on the 5th wheel, now no more guessing as to level.

great item eazy to apply

I was sorry we had to return the item, the ball stuck and played catch up. Other wise it would have been perfect for our application. God Bless

似た商品は持っていますが、一般的なモノより傾きを敏感に表示するので平行して使用しています。 しかも2つあるので車両の前後方向と左右方向の傾きを見ることができます。

Does the job but only measures up to 30 degrees
