Based on my research, the Dexter Trailer Hub and Drum Assembly #8-201-5 will replace the 3160121 drums on your 2003 Airstream Classic. This assembly is designed for 5,200 pound axles and features a 6 on 5-1/2 inch bolt pattern. I have attached an…

Hello Eric. For the SeeLeveL Sensor for RV Holding Tank Monitor #SE78VR, the blue wire is for the tank sender signal and the black is for ground. As long as they are wired correctly, they will work with any monitor including your ESP8266.

Hey Ed, The SeeLevel Tank Monitor 709-P3 can be purchased under part #SE44VR and the 710-AR sensors can be purchased with part #SE88VR. These are all sold individually so you would need to get three of the #SE88VR to have one for each of your water…

When this has come up before, ThermaHeat recommends removing a portion (18-1/4 x 12 in this instance) of the insulation on the tank large enough to install the #277-000164 heater so it's in direct contact with the tank. You're correct,…

Here is the wiring diagram from SeeLevel for the Monitor #SE94VR. I hope this helps you clear things up and get it working.

The particular load range of trailer tire needed for any given application depends on the number of axles and tires. If a trailer were to have, for example, two 3500-lb-rated axles, then it would likely have a gross weight rating (GVWR) of about…

Thanks for the picture and info on your current brake assemblies, from that we know that the Dexter brake assembly part #23-106 that you referenced is the correct fit. For the left hand side you'd then want the part #23-105.

Joe, I was able to track down a diagram and find out that the Telesteps Telescopic A-Frame Ladder #TE37FR is 15.4" wide all the way up and down until it reaches the base where it extends to 30.1".

I spoke with my contact at SMI and the piece you are looking for is #SM99625 which is the fitting and the bracket. Or if the bracket is still fine and all you need is the fitting you just need the part #SM99726.

Mike, unfortunately not. The SeeLeveL Sensor for RV Holding Tank Monitor #SE78VR is designed to be used with the SeeLeveL RV Holding Tank Monitor #SE34VR, so it's not going to work with your Simarine Pico Tank Monitor.
