Finally... I have completed the RV-Project Trailer Test Set V1.5. The video for it will be published sometime in April 2022. The video to be published in April will be the construction video, with an operation video to be published a bit later.

After the video publishes, I will try and make available a parts kit for V1.5. This will not be a complete kit, but rather parts that are hard or costly to obtain. For example, some of the parts have a minimum quantity, including the circuit board, relays, cabinet feet, and other components. I will bag those parts together and sell them as a parts kit so that you will not have to buy the extra quantity and have stuff you do not need.
In addition, I will include the 3D printed parts for the relay bracket and switch wafer. I plan to have one or two parts kits available, but depending on my stock on hand, the actual components may differ. For example, I may have 6 mounting feet available. Since each project requires 4 feet, one parts kit will have the feet, and the other parts kit will not. I will describe those differences and price accordingly.
The parts kits, when available, will be at the RV-Project "Items for Sale" page. I cannot guarantee whether or not the parts kit will be available on the release date of the video. I had hoped to get that done, but dang it! I have been fighting a cold for the last 5 days. The last 6 months sure has been a struggle. The best I can tell you is to monitor the website for an updated blog. Or if you are subscribed to my RVProject YouTube channel, I will likely post it there too... in which case you will be automatically notified.
I will begin construction of the Trailer Test Set V2.0 soon.
