I think if space and weight aren't pretty major concerns, AGM still makes sense for most builds. Efficient charging and long lifetime of Lithium may be good reasons for some as well (e.g., full-timers living off solar). Yeah, interested in the energy usage of the heaters too, I'll try to track...

So, as the LiFePO4 geeks among us know, charging is strictly forbidden if the battery is below 32 degrees F (0 degrees C). Doing so can lead to total loss of the battery. I've been playing with fire, a few times on ski trips and on our last four corners trip, I probably came close to charging...

Hadn't seen this before, looks really promising for a small camper. I too am very interested in anyone's experience.

I went with the flexible panels for the same reasons you listed plus the lighter weight. My results are mixed. A Suaoki panel off amazon went bad in under a year (the clear film on the outside of the panel degraded and started pealing and the efficiency of the panel approached zero). Other panel...

Okay, time to get the Maxxair fan up and running again. They sent me a new board. No instructions but pretty straight forward replacement. A little searching on these fans turned up two known weaknesses that will apparently fry the board: 1) moisture and 2) highish voltage. The small camper can...

Looks like Photobucket is down for lots of people or everyone. No need to freak out man. Lots of us spend a fair amount of time posting here to help other builders out or entertain fellow camper nerds - if my way of posting pisses you off, plenty of other places to go on the web :)

Well, 10 days since I sent a message to Maxxair about the roof vent fan and no reply. Not happy. Sent a follow-up message to give them one more chance, but I'm not optimistic... Edit: Got a quick reply to my follow-up message. New board on the way under warranty

Part two of the recent trip... With the weather coming in, we decided to head for lower elevations - west towards Hovenweep NM. Pulled in to an almost empty campground just as the sun was setting on Thanksgiving Eve. The next morning we walked the trail and checked out the ruins. Forecast...

Yeah, just makes sense that it would be less efficient heating, say, 25 degree air (from outside) than 60 degree air (from inside) - I don't have a good handle on how big that difference is. I think the fresh air intake you're referring to on the Propex is just for combustion (i.e., to feed the...

Needs more testing. We ran the external intake one night and it seemed like the heater ran more frequently (i.e., less efficiently), but can't be sure of that. In general, we were in pretty dry atmospheric conditions so we were getting minimal condensation with the heater recirculating and the...

I got my panels from Carbon Core. They ship but 4'X8' panels usually ship freight so may not be cost-effective for a small order. No big box options that I know of unless you want to buy foam from them and do you own fiberglass skins. Lots of ways to do corners - Aluminum angle with the a proper...

Few select pics from the trip... First night made it to almost Flagstaff. Free camping, chilly night. Oh yeah, note the new truck! Decided it was time. Looked at all the new mid-size truck offerings and the only one with a bed wide enough for Pro-Rig is the Nissan. Made the choice easy. The...

Thanks, good to know I can expect a reply. Any advice on conformal coating? New to me - Google search showed lots of different materials you can use. Is there just one board in there?

Final step in the battery was to put a box over the new half of the battery. Space is tight so I went with 1/8" plywood with 1/16" angle holding it together. Funny looking shape, but it gets a coat of "Pro-Rig White" paint. Final look: Wedges in tight and there's room for a small basket on...

It was a bit hectic getting out of town so just getting around to finishing the update here... Final step on the new pop-up material was gluing on a flap around the edges with the second layer of velcro for attaching around the edges. Also sewn in to the flaps are shorter pieces of velcro...

We're less than a week out from our first proper winter trip in the camper. We've got about 10 days over t-giving week and we decided to hit the four corners region. Hoping to see some of the touristy areas without the usual summer crowds and get off the beaten track and have some spots to...

Batteries first then! So, I'll admit to feeling battery capacity anxiety with the current 100Ah LiFePO4. A big part I think is the electric water heater which uses about 35 Amps to get water heated up. There's been several nights we've gone without hot water to conserve Amps. I've been...

Thanks Karch! Good time to revive the thread as upgrades are happening. The teasers: Updates to follow...

Yeah, only done these warm and dry trips lately so no condensation testing. I never got to test the external intake for the heater (i.e., no later season ski trips :cautious:)

Couple fun trips to report on... First is from a while back. We did chase the tail end of the super bloom down at Anza Borrego back in early April. We managed to coordinate with some fellow camper builders from just up the coast and found a quiet remote camping spot. The big and the small of...
