  1. Seriously, if anyone is in the area and need a place to stop for a couple of days you are welcome. I can help with small projects.
  2. Driveway is available most of the time. 😄
  3. Finally got all of the ceiling panels up, it's only been 10 years, never rush into anything. Needed a new dome light, made this out of an old glassm bus dome light, Cut afixture out of walnut and converted it to LED.
  4. Just curious, if the CAC is completely plugged, why is the engine not overheating? The air that cools the engine passes through the CAC.
  5. Why is this conversion taking so long? It's only been about ten years. I seem to take time to learn new skills because I want to build something. Too cheap/broke to buy them. I spent the winter milling lumber. My woodworking skills have improved a great deal. I'm now using walnut and ash for the interior. Here's a video of what I did to get some walnut trim pieces.
  6. I gave this a bit of thought when I first started building my tow setup. I decided there just wasn't a need. This is a fairly good presentation of my setup. A couple of notes. My towed is old so, rock chips in the paint are a minor consideration I have a pusher bus, rear bumper is 24 inches above the ground. My tires are 38" in diameter. Towed is a Ford Ranger so, hood is pretty high. There are so many variables such as vehicle speed, wind, surface to make any kind of prediction. I couldn't really find any graphics of this. This is only what I think. Red line is the path something would have to take to hit front of vehicle. I don't think this is the likely path anything would take unless you were to spin the tires of your MH. 😁 This shows no drop of any kind. Green path is what I think is much more likely for anything coming of of a tire.
  7. I have Victron and like the idea of using with my phone. I also wanted a coach mounted display. I bought a cheap tablet with bluetooth and, with a voltage reducer, mounted it in the living area. I also have bluetooth light and awning controls as well as information from my home built BMS for my lithium batteries. I can monitor everything from one unit. As an added bonus I can send data to my computer from the tablet.
  8. Technically an LED will work on AC voltage if you get the voltage right. Since it is a diode it only lights on every other cycle. The 12v strip LED's are available in both water proof and non waterproof strips. They make connectors that snap on but, I've had better luck just soldering a wire to the copper pad. Many of the fixtures I have made use one of the led boards made to replace automotive lights. One example. They already have the resistors needed to make it work with 12V. Just remove the plastic plug and solder wires on.
  9. Made some new LED light fixtures. Top left is walnut, right is pine, bottom right is cheap plastic original fixture.
  10. These aren't fluorescent, they are aluminum channels about 1 inch wide that you put an led strip in. LED fixture
  11. I just finished the control/information panel made of solid walnut. Monitors solar, LiFePo batteries, boiler control, as well as switches.
  12. I'm pretty excited. I got everything wired and working yesterday. About noon I turned on the AC in the bedroom. At about 6PM the panels were still producing more than the AC was using. (Northern Indiana, slightly cloudy, some overcast). I left the AC on all night set on 75°. This is what the state of charge was this morning at 6AM 12,000 BTU inverter type mini-split 6 255W solar panels 6 138 Ah Valence LiFePo4 12V batteries Home built safety for battery shutdown along with Valence cell balencing All of this started about a year ago when I saw an ad for some used Valence batteries. At that time I knew nothing about lithium batteries or solar. Rough cost $5000 including batteries, solar panels and Victron inverter/charger and solar controller.
  13. Another step closer. My son came and helped to mount the solar panels. The original luggage rack was exactly the right width. It was two rails tall and with a little cutting and welding the top rail went forward to mount the front two panels. I did repaint the roof after I took this photo. 1530W, still have to finish the wiring but, this is the part I couldn't do by myself. __________________
  14. I also have a ReadyBrake and like it a lot. Much nicer than the old system that had a vacuum pump that sat on the floor. If all you are concerned about is break away safety the ReadyBrake break away system would do it with nothing else to purchase. ReadyBrake break away
  15. This is all done and installed for testing except for actually hooking up the main relay. It has changed a bit since my first post. I've added a temperature sensor inside of each battery. It logs to a memory card and sends data to my phone via bluetooth. I was surprised to find that I can get the data from inside the house.:smile: Unfortunately, now that it's spring I can't test the cold weather part but, I did thoroughly bench test it.
