Magnum MMS1012 PSW Inverter Upgrade and Lifeline AGM Batteries Replacement

 

Our 2011 RT Agile came with a Tripp Lite 750 watt inverter/charger from the factory. It works ok for the most part, but the built-in charger has limited charge parameter setting especially for AGM battery which we had.

The factory installed coach batteries (US Battery AGM2000) lasted us about 6 years, until it was “cooked” by the Tripp Lite charger during our recent summer roadtrip. I was able to temporarily replace it with a Walmart battery the following day, and that saved us the rest of the trip.

Overhead LED Lightning Conversion plus LED Mood/ Party Light Combo



The interior fluorescents lights were actually converted to white LED’s a few years back and the Wi-Fi/ BT/ RF controlled RGB LED mood lights were added recently. Both LED lights are independently controlled and can be switch on at the same time for extra brightness.

Parts used: (Amazon product links)

• WiFi/ RF/ Bluetooth LED Strip Controller
• 4 Color RBG Extension Cable Line
• RBG LED Strip Lights SMD 5050
• 12 volt inline Fuse Holder

Fixing the Drippy Bathroom Faucet in our Agile

Our bathroom faucet started leaking around the handle so I decided to disassemble the faucet to see what’s causing the leak. Here is how I did it.

First turn the water pump off, then open the faucet to release the water pressure. Remove the handle lever. The handle is held by a single screw hidden under the red/blue plastic plug. Using a mini screw driver or something pointy, remove the red/blue plastic plug on top of the faucet handle.

DIY Hitch Cargo Carrier and Side Mounted Hitch Receiver for Roadtrek Agile

Agile's Continental spare tire carrier location prevents the use of hitch cargo and bike carriers without any modifications. I've seen people use hitch extensions to clear the spare tire carrier, but this defeats the purpose of buying the shorter Agile not to mention its considerable influence in dynamic loading of the rear suspension over bumps and other road changes. Hitch baskets and bike racks mounted towards the rear of the spare tire also prevents the spare tire carrier to be folded down when needed.

I fabricated an extra hitch receiver that bolts-on into the right side of the factory hitch arm; it can accommodate medium sized hitch cargo carries/basket.  I will be fabricating a hitch cargo/bike carrier combo that swings to the side for easier access to the rear of the RV. For now, I'm using a small fabricated hitch cargo carrier for small loads like firewood/ ice cooler/ tool box, etc.

The receiver tube is a Harbor Freight tube cut short, and then welded to the fabricated bracket.

Automatic RV Hot Water Recirculation System

To minimize waste of water while waiting for the hot water in the sink or shower to come through, I installed a DIY automatic hot water recirculation system in my Agile. I can also use it to prevent the water line from freezing when camping below freezing temperature. I'm already thinking of re-plumbing the hot water line under the RV to provide heat into the fresh and holding tanks via a DIY heat transfer plates which will be installed under each tanks. A manual diverter valve will be used to divert hot water away from the heat transfer plates when it is not needed, that would be my near future project.

The DIY hot water recirculation system is installed into the galley faucet hot and cold water line which is the point farthest from the water heater. It is fully automatic with manual switch override. A digital temperature controller is used to switch the pump on and off to automatically recirculate hot water back into the cold water line. The adjustable fan-control thermostat switch (see below) monitors the water temperature in the water heater tank and the system only becomes active when set temperature is achieved. It will shut the system off when water temperature falls below the set temp, doing this will prevent the recirculation pump to continuously run when water heater is shut-off and hot water falls below a certain temp.
