Comments from customers who have retrofit our RV Tank Monitors

  • Tom, Received the unit Friday morning and installed it on my 3650 Cruisers on Saturday.

    Works Perfectly !  Was easy to install and wire.

    You have a great product, and 4 other boaters in the marina have already looked at my system.  Thank you

    —Glen Blake,

  • I have just had installed on my fifth wheel trailer a set of 709-4 tank gauges. This is the second trailer I have had these gauges installed on and they are the absolute best. The set on the first trailer remained accurate for years until I sold that trailer. The gauges they install at the manufacturer in most cases are fairly useless and inaccurate. I would gladly pay extra to have the Garnet gauges installed at the factory. I have had occasion to contact your Customer Service and found them to be helpful and responsive. Thanks for providing a great product! Now my wife won’t run out of fresh water while in the shower. You simply can’t let that happen more than once!

    —Bob Haynes,

  • Great product – I should have installed one of these about 55,000 miles ago (we have 60,000 miles on our 2005 Itasca Horizon 40AD) and we’re anxious to use it while we’re on the road all summer!

  • I thought I’d send you folks a link to an installation article I posted on a RV forum website I am moderator on. I thought some of the folks comments may be of interest to you.

  • The SeeLevel recreational vehicle tank monitoring system has been, for quite a while now, the leading digital display system on the market. Other systems have been introduced, but none with the accuracy, features, and ease of installation of the SeeLevel. I’ve been such a fan of it that I have recommended it be installed in family and friends coaches as well having it in each of our previous motorhomes.  Here is an install of a 713 system on Joe Kasunich’s new Allegro Bus motorhome:  www.irv2.com

  • We have a 2006 Beaver coach with a Aladdin System which gives us all kinds of information such as all engine functions, rear view camera, temperature and much more. The problem was everything worked with the exception on all the tank monitors

    would not function. I took it to a couple of different repair facility’s trying to get it repaired only to be told no parts were available.

    I read the article in FMCA a couple of months ago about SeeLevel gauges distributed. By Garnet Technologies Inc. at Granbury, Texas. May I say this was a very pleasant experience dealing with this company.

    I called Cary at Garnet at 877-668-7813 and made an appointment to have their SeeLevel system installed and boy am I glad I did , this is a very professional run company that goes way out of their way to please the customer. We had a problem during installation with my existing Aladdin system that was not their fault nor did they cause the problem. They went way out of their way to correct the problem and didn’t charge me for all their time, when was the last time that happened to you. I can’t say enough about the help and concern Cary and the Owner showed for us. I do not think you can find better service anywhere.

  • The sensors themselves are trouble free. No more fouling issues. … The information is very accurate and displayed on an easy-to-read LED panel. An easy DIY installation makes this an attractive upgrade for any RV owner who wants trouble free accurate information, this upgrade easily makes our “A” list.  Read complete article here.

    —Bill and Jenn Gehr,

  • I just want to thank you for having great people in your employ!

    Last Friday when I asked for help with my black tank issues in my Leisure Travel Van, I got an almost immediate reply to my question.

    Don Shapansky replied to my email almost before I sent it. He went into great detail to try and help me diagnose the inoperative sender on my holding tank.

    I have replaced the faulty sender with one that LTV/Triple E had sent to me and now my system is up and working correctly.

    It’s makes things easy when you have a great coach!

    Thanks again!
