Simple Auto Deploy TV Antenna Reminder

You can buy a TV antenna reminder clip like this "Clip-on Antenna Saver" or make your own. The problem with the clip-on antenna reminder tags is if someone forgets (ohhh... the irony) to hang them after raising the TV antenna. If you have kids like I do, believe me, they will "intentionally" forget.


So, I designed and patented (jk) this self-deploying antenna reminder. All you need is a line ( a fishing line, pull chain, etc.), fishing swivel (optional), instant glue, a small magnet, and a small item to hang preferably with striking colors or maybe a glow in the dark item; the choice is yours. The hanged item will serve as your reminder that the antenna mast is up.

Here is mine.

200 Watt Solar Panel Installation on Roadtrek Agile


I’ve been eyeing on AMSolar Sunrunner Signature System kit for a while and when they had a holiday sale last year, I grabbed that opportunity and ordered (2 )GS-100 solar panel kit, a SunRunner Signature 25 MPPT/6/ Pro Core kit, and a combiner box. Other needed items were purchased on Amazon, like the hydraulic crimper, a Sikaflex 221 sealant, etc. The AM solar kits were pretty much a complete set; you just need appropriate tools to complete the install. If you have questions, give Dave at AM solar a call, they are very nice people.

Protecting the Fresh Water Tank/ Water Drain Fitting and the Gray Tank from Road Debris.

The location of the fresh water tank and the drain fitting at the front passenger side wheel well is highly vulnerable to damage from road debris the tire spews at it. The front facing wall of the gray tank is no different; it gets pitted and sandblasted from road exposure. I covered the exposed areas of the tanks with an anti-fatigue mat few years ago using plain silicone adhesive sealant and it held up and protected the tanks well for thousands of miles.

The fresh water drain although now protected by the mat, it is unsightly and needed an update and extra protection. I got the idea from a sprinter-source forum member (credit goes to Mein Sprinter). I bought an inexpensive plastic splash guard cover (pictured below) from a local auto supply chain. Pre fitted into the wheel well, I marked the area of the splash guard that needed to be bent inward to prevent it from rubbing against the wheel.  Using a heat gun, I slowly and evenly heated the marked area and while it is still warm, I slowly bent it inward by hand and then let it cooled down under running water. The splash guard retained it shape and was a perfect fit with no trimming needed. I slathered a good amount of silicone sealant along the top J-shaped edge of the splash guard for extra hold then secured it in place using 3 screws.

Upgrading Dometic Penguin Duo-Therm AC Analog Thermostat to Digital Single Zone Wall Mounted Thermostat.

While cleaning the AC air filters, I noticed 6 unused color coded wires inside the air distribution box. I'm pretty sure I noticed these wires before but really never paid attention to it. I tested the red and black wire for power and was surprised that it has live 12 volt power. I contacted RT but they never gave me a straight answer, so I traced the wires and 5 of the wires terminates into the rear of AV overhead compartment close to where the furnace thermostat is. Obviously it is pre-wiring for the electronic AC thermostat control.

I called Dometic and asked if I can upgrade my current AC (Dometic Penguin Duo-Therm with heat strip option model) to a single zone digital thermostat wall mounted control. I was given the part numbers needed for the upgrade. I was told that I needed the electronic control box (Part # 3313270.000 with Heat Strip option) and I also needed to change the air distribution box in order to mount the electronic control box inside. The air distribution box that came with the RT is a low profile model and does not have enough space for the new electronic control box, but I do like it because of its low profile design.

I bought the Dometic Single Control Kit (Part # 33313270.000) from Ebay. The kit came with the electronic control box, single zone LCD digital thermostat, a manual, and 4 mounting bolts.

Accessing Rear-View Camera Wiring Harness for Troubleshooting or Camera Replacement

My 2011 Agile came with an Eclipse GPS Navigation and Audio System; it is also equipped with a rear-view camera. RT has installed a generic camera in lieu of the more expensive Eclipse brand camera. I have read somewhere that the original Eclipse camera is powered by the head unit at 5-volts. In order for a 12-volt aftermarket rear-view camera to work, RT used an adapter and spliced a 12-volt power from the Sprinter reverse lights. One drawback of using an aftermarket rear-view camera is that you loss the manual "always on" camera feature of the unit.

Recently, my rear-view camera intermittently stops working at night, especially when it gets cold. The camera would start working again when it gets warmer during the day. I thought there must be some loose wiring connections to the camera that possibly exacerbated by moisture or condensation build up. I pulled out the head unit and replaced the loose push-in Coax-to-RCA connector for the camera with a better compression type, but that did not solve the problem. I called RT on how to access the rear-view camera wiring harness and was told to remove some panels just after where the camera is mounted, but Agile has a rear overhead cabinet on that area and that would be a pain to remove.
