Review on Enhance Your RV with RV Designer E401 Exterior Hardware by Darryl Montagna

I have purchased three (3) of these kits and am in the process of purchasing another one. I remove the glass tubes and only use them when I need to park my trailer. The rest of the time I leave the glass level in the van or at my house so it doesn't break on me. With all the problems these spirit levels have, it would be nice to be able to buy a replacement glass spirit level in bulk and just keep replacing them when they break. which happens frequently and in a very short time. PROS: They really work GREAT! VERY quick, easy to level my caravan with. : POOR CONSTRUCTION/NOT QUALITY - DO NOT WATER AT ALL due to the height of the glass bubbles (if installed OUTSIDE the caravan!) - The sun will heat the bubble tubes and they will break - They may vibrate while the trailer is being towed NEED TO BE REPLACED FREQUENTLY
