You would not be able to charge your battery through the wiring on your 4-way trailer connector. Since your truck has a 7-way connector, you could maintain the power to the battery but not charge it. To begin, you would need to cut off your 4-way…

Hello Al, thanks for reaching out. The OptiMate Lithium 4s Smart Battery Charger #MA47JR can indeed be used with the Zamp port on your Casita Trailer. You will just want to be sure your zamp is wires correctly for this charger. Zamp likes to wire…

Hey Gary, so a charger like the NOCO Genius Multi Bank Smart Charger part #NOC24FR would work great to keep both of your batteries topped off and charged when in storage as this was designed for charging two batteries.

You can put a maintenance charge on your trailer battery with the 12 volt accessory circuit of the 7-way. The 1:00 position of your 7-way carries this circuit. You would just need to run a length of 10 gauge wire like part #10-1-1 (sold by the foot),…

For a 3,000 watt inverter you'll need a 300 amp hour lithium battery like the Go Power Sun Cycle Advanced Lithium RV Battery item #GP26QR.

For a 12,000 lb. electric car trailer winch like the Bulldog Winch Trailer Winch part #BDW10040, I recommend a standard 12 volt lead acid battery rated up to at least 650 cold cranking amps (CCA). As long as the battery is rated up to 650 CCA then…

The Redarc BCDC Charger part #RED36TR can work with your fridge but it wasn't designed to power accessories directly. You could use it to charge your 12 volt battery that is then powering your 3-way fridge on DC mode though.

I've contacted Brightway, who forwarded me a copy of the instructions they include with the #BRW77FR switch mode charger. I've provided a clip showing the instructions for you.

Hey Mark, The 30 amp Portable Power Watchdog Surge Protector with Bluetooth, Wi-Fi, and Emergency Shut Down #HU42VR weighs 6 lbs and measures 19" including the cord, with the body measuring 12" tall; it is also 6.5" at its widest point…

Hey Gary, yes that does sound like a switch is at fault. I am not sure which Lippert jack you have but we do have the replacement switch part #LC49MD which does fit Lippert jacks. If what you have looks different email me a picture of the…

You did you homework, yes the 40 amp fuse size of part #331-FK60 is correct to use with the Redarc Manager 30 system part #RED93FR and the Redarc Smart Start Battery Isolator #331-SBI12. These three components would work well together and would be…

Hey Phil, so since we know you have 10 inch octagon jack feet on your 2025 Jayco Alante 29s the SnapPad EQ part #SN76FR is for sure the correct fit. The Stromberg version is called the Base Pad Shoe and it looks like a horse shoe to me almost. I…
