I went up on the roof of my trailer today since it was 70 degrees here!!!
I made a heavy paper template 41x21 just like the Renogy 100 watt flex solar panels. I have room for 3 panels on the center section of roof between the two fans and I actually have room for 2 more in the front. I think this means that I need to think about getting a controller capable of handling 500 watts which would be 30A. So now I'll probably get a Morningstar Prostar 30.

I finally got around to registering my trailer and getting the title transferred. Now I can drive it around. Anybody have good ideas of how to attach the plate? I'd rather avoid more holes. I'm wondering about VHB tape.

timzog,
I've been running 2 Renogy 100w stiff panels for a couple of years now and they have been working very well. I'm thinking about the flexi panels next to add another 200W.

I did some shopping this week. I purchased a C-Head composting toilet, 2 Renogy 100watt flexible solar panels, and a Morningstar Sunsaver Duo 25a controller with a remote meter. More details as stuff starts arriving this coming week.

Starting on the solar install. Here is the Blue Sea switch I will use. I have it wired to the battery as the common and the charge controller as 2 and the power center as 1. Click image for larger version

Next I wired up the Morningstar sunsaver duo. All the ground connections are common so I used that to ground the battery and the solar panel. I have #6 wires from the solar pass throughs on the roof and #6 wires to the Blue Sea switch. Click image for larger version

It fits well in the space.
To ventilate it I took a 1 1/2" abs make threaded fitting and screwed it into a 1 3/8 hole in the top right side. I just enlarged the hole a bit with a file until it screwed in perfectly. I used 1 1/2" pipe since it has much bigger cross section than the 1" that came with the toilet. This went into the sink cabinet and was Teed into the vent stack from the grey tank.
The vent stack was connected to the the 1 1/2 elbow of the vent fitting with 1 1/2" spa tubing from the big box store. It threaded perfectly into a 1 1/2 x 1 1/4 threaded sink fitting. Click image for larger version

I purchased a 40mm 12v fan and filter to install on the toilet end of the vent.
The Noctua fan is super quiet and has a 0.05 Amp draw so it will use only 1 Amp hour per day.

1980 Caravelle Shell Off Renovation

Renogy 100 watt flexible solar panel install.
I purchased 2 of these panels for about $210 each.

To install on the roof, I cleaned the roof surface with acetone, applied VHB tape at all the comers and trempro along the entire perimeter.

I peeled off the tape cover and carefully stick it in place on the roof.
I used a j roller to stick down the tape and gently pushed around the perimeter to stick the trempro sealant and then put everything in the garage on there to hold it down.

I attached the wires with a Y coupling that used the original MC4 connector. I cut off the end and attached a ring fitting and sealed with heat shrink.

These were connected to the 5/16 Blue Sea pass throughs and tightened after application of antioxidant pasta and then connected to the panels.

I am not happy with the cable management and seriously considered cutting the panel cables to the right length but that would void the warranty.
Cleared off some snow today and got 1.18 amps at 4:30 PM on an overcast day.

Super nice work! You have good taste in the items you're using in your trailer. I really like how clean those solar panels mount.
Thanks for sharing.
Mike

Thanks Mike,
My concern with these solar panels is that they will have a short life time and I will have to scrape off a 12' long bead of Trempro sealant. I'll try to do some analysis over the next couple of years to see what happens. On some flexible panels, Lewster, who knows way more about solar than most people especially me, has observed cupping of the surface material around each cell which resulted in little puddles that end up forming dust spots when they evaporate reducing power. I was very close to buying a 300 watt LG grid tied panel and an MPPT controller, but I wanted to avoid putting 40-50 pounds on top of the trailer and raising the center of gravity. Also, the aerodynamics of the flex panels has got to be way better. I was imagining wind whistling underneath a rigid panel on a windy night
The total cost of my solar install including the switch, the controller, the 6 awg wires, and the pass through connectors is only about $700. With the Sunsaver Duo and the space on my roof, I could add 200 watts more power, but I'm going to watch for a few years and see what happens to the technology. I'm sure something will come out next month that will be vastly superior, but I'm going camping in 2 months and I've got to get everything functioning.
My long term plan is for a DC only fridge but I'll probably need more panels and possibly another battery for that.
Tim

I ordered one, but it hasn't arrived yet. It is a 40mm 12V fan that will mount over the inlet of the vent pipe on the inside of the toilet. The C-head manual says it is not needed unless you are a heavy user but I'd rather err on the side of my Airstream not smelling like crap The fan I ordered is the following: Noctua 40x10mm A-Series Blades with AAO Frame, SSO2 Bearing Premium Retail Cooling Fan NF-A4x10

It is supposed to move 4.8 CFM at 18 dB noise with a 0.05 amp draw. That means it will use about 1 Amp-hour per day. I also ordered a cheap 40mm filter to mount on the inside of the fan which should keep the fan and the plumbing clean. With the solar panels, I am expecting to just let it run all the time. Hopefully it will provide enough exhaust flow that I won't need the fantastic fan to keep the humidity down on a cold night. My fantastic fan is the 3 speed model and it uses more than an amp on it's lowest setting. I'm tempted to upgrade to the variable speed replacement that uses 0.2 amp on it's lowest setting but it would cost almost $200. May also be better to exhaust cold air from down below instead of exhausting hot air from above?

Need help with exterior door lock/closure

I posted this on the lock thread too, but I wonder if anybody on this forum might have some ideas about this. I just ordered a deadbolt from VTS that has the extended smaller bolt This allows for a much smaller hole in the door frame than most deadbolts and will be adequate for security and prevent the suicide door from flying open on the road. My current lock is a very standard RV lock installed hastily and horribly. I'd like to remove the lock, patch the outer skin, and replace it with a very simple door closing and opening mechanism that doesn't have a keyed lock at all. The deadbolt will provide security so my goal is for easy quiet access in and out of the trailer. Since it doesn't have to lock, options could include things like magnets, door knobs (rather not), some kind of door latch. The ideal system would be something where the door would be pulled tight by the rotation of the latch instead of engaged by slamming. This could be way quieter and more reliable than the current system. Again, the deadbolt provides all the security, this system would just need to hold the door closed when you are at camp to keep out the elements and bugs and to allow for easy and QUIET opening and closing. I am willing to go outside the box. I also need to replace my door inner skin so there is no problem if it requires modifications to the door.
Please help

I haven't posted in a while since every spare second is getting ready for our first trip this coming weekend!. We bought a new Honda Pilot to replace our old one and feel much better about the 4500 pound weight limit for our trailer that should weigh 3000-3500 pounds loaded. In the past month or so I've installed a VTS deadbolt, made and installed new curtains, built custom rear stabilizers, set up an EazLift weight distribution system with friction sway control, rebuilt the main door, worked out a shower curtain, installed some IKEA wire mesh drawers in the main cabinet, and installed a brake controller in the new TV. I have to renew my membership to post more pics, but it hasn't been a priority as In get ready for our trip.
Any advice from the more experienced RV people out there??
