I just hooked up the little fan. It's 60mmx60mm and it has a max airflow of 12.7 cfm. I can barely feel the airflow. I also double checked my measurements. If I do the ceiling mount, the edge of the roof vent for the toilet will be 12" from the corner of the MaxxAir fan. Given how little air...

I do also have a roof fan at the rear of the trailer which is above where the bed will be. I imagine that in most cases I will have the rear fan drawing air in and the front fan above the toilet blowing out for good airflow. The front fan will probably almost always be blowing out to help draw...

My v-nose cargo trailer is about to have a composting toilet installed. It will be all the way up front in the center of the "V". I'm working through the best place to install the vent/fan exit for the toilet. The three obvious choices are: 1. On the ceiling covered with a typical plumbing roof...

After a bunch of searching I think I have a workable plan. I'm going to use the Valterra waste valve that terminates with 1.5" male pipe threads. When needed, I can use the Valterra Gray Water Drain Connector that allows you to attach a standard 3/4" water hose to the 1.5" threads. This allows...

Thanks but I only have a gray tank, no black tank. But it sounds like you are saying that the dump station and RV hook-up all have a 3" connection. Correct?

I'm working on a cargo trailer conversion (though this applies to any vehicle I think). I will be mounting a gray tank underneath. It has a 1-1/2" outlet. I'm trying to find what I need from there that will allow me to drain the gray water properly. I know I need some sort of valve (such as...

You mean I shouldn't be using it with the door open in AZ as an A/C? ;) Lots of labels. Good reminder.

Thank you. You make good points. It seems obvious once you learn it but not before. :) Thank you. Good info

Thanks but no. I understand how to do the different combinations of wiring, I'm trying to understand which way may be better: 2S2P or 2P2S. BTW - the wiring in that image isn't ideal from what I've seen. The two wires going to the controller should come from opposite ends of the two serial...

I'd appreciate it if we can please keep this thread on topic. I don't wish to start a 12V versus 24V electrical system discussion in this thread. Feel free to start a new thread if desired. Thanks. Any thoughts on the pros/cons of wiring either a 12V or 24V version of a device (when given the...

See  from Will Prowse for a good (to me at least) explanation of 12V versus 24V solar electrical system. Hence my use of standard 12V plugs in my system.

I'm working out the nitty gritty details of a planned 24V electrical system in a cargo trailer conversion. Part of the system will have a DC-DC converter to give me a 12V fuse box for all of the typical 12V items such as lights, fans, and DC outlets. With that in mind, I'm trying to figure out...

I'm just starting to delve into the world of solar. I have a question about combining batteries. As an example, let's say I have four 12V 100Ah LiFePO4 batteries and I wish to wire them to make a 24V 200Ah setup. I see two options: 1 - Wire two in series. Wire the other two in series. Each...

Oh yes, I did misread their suggestion. Now that's an interesting idea to consider.

That may be part of it but it's not that simple. There are two doors. For the RV latch to work at all on one door, the other door needs to be latched shut is some appropriate fashion.
