RV T Levels, Cross-Check Bubble Level with magnetic, For RV, Motorhome, Travel Trailers Front-to-Back, and Side-to-Side Leveling, Durable, Waterproof (Black 3 PCS)

I put these a few inches in front of golf holes. They can indicate breaks that you won’t see.

Not as accurate as a longer bubble leveler but we don't want to always have the long leveler out. So this does the trick and helps with leveling.

Magnets works great, their small(one can fit inside of your palm) and they are very accurate.

These are great levels at a great price point. They are built very well and easy to see. They make leveling our travel trailer a breeze. Truly a step saver!

Well made. Decent strength magnet. Great for leveling my camper trailer.

Buy something with numbers. I'm not out much cash but wish I never installed them. If I remove them, I will have holes. About zero chance of finding a replacement to fit holes. Might get bigger and cover over the holes. The levels with 1 2 3 numbers show's how much unlevel trailer is. The up and down is easy to adjust with the trailer jack. A little hand level inside in center is best for side to side. About as easy as walking to both sides of trailer, better if it's off much.

These came in a pack of three or 4. I used them for the first time and none of them would be level at the same time side by side. I had to take them out of the magnet case and use the cylinder alone to achieve level. Waste of my money.

I bought this to replace a previous T-level on our camper trailer tongue. These are total junk. Compared them against a real level and they are way, way, way off, both front to back and side to side. Don't waste your money.
