RE: Solar with Lithium Battery
Yes, change your solar controller settings so it won't do more than 14.6v, and kill any temp comp for the same reason--nothing above 14.6v ever. No "equalize".
The sun won't shine any brighter by changing to LFP from your FLA so ignore all claims about "faster charging" with solar if only you swapped to LFP.
In the same way, a 55 amp converter will not do more than 55 amps either if you swap to LFP. Engage brain before believing the advertising! :(
You will get more usable AH but not twice as many. From a 100AH batt you will get 80 instead of 50 by following the guidelines for each type.
(20-100 vs 50-100)
Watch out for high temp limits on the LFP since you say Pueblo it might get hot there. Also low temp limits at night?
To go camping off-grid you need more than 100AH or be a tent camper, so that means you will need two of those very expensive LFPs, not just one. That also means your one batt now is not enough. Get your wallet out for a second one of whichever you choose.
A 100w panel will help a little but not much. 200w can do a useful day's work.
Now the good news! :) LFP works well with solar, because you don't have to get back to 100% SOC every day. Solar can kill FLAs for this reason, that the sun goes down before the batts get truly full, which eventually kills them from sulphation. No worries about that with LFPs (or SiO2 for that matter).
Also Battle Born is not the only pebble on the beach.
Faster charging is true since there is no absorption phase, just bulk.
Since the op went with a battle born they do get 99ah usable. Someone cut one up and found they built the 20% into the number of cells. So they actually have 120ah of cells inside.
I agree 200w would be better but you can always give it a try and add if needed.

RE: Lithium and DC-DC Charger?
I use a victron 12/12 9, I think it's 120W so about the equivalent of 1 panel. The truck may be 10ga, hard to tell but I think in the camper and umbilical were 12 so this model is plenty safe. I get 7-7.5A out of it at 14.6V.

RE: Lithium and DC-DC Charger?
I went without vehicle charging for when I switched over, I only used solar. No problems until the fridge upgrade.
I use a small one now on factory wiring and would recommend it if you want vehicle charging. This will keep the voltage stable as you don't want the BMS to disconnect on over or under voltage from the alt.

RE: "Newer" Ford trucks don't charge house batt's?
the quality of flooded lead acid batteries has gotten really bad ever since the gov't cracked down on lead in the US. Most are not made here anymore.
I've been in the desert for 28 years, if a flooded battery in a car makes it past 3 years I consider it a gift and replace them. I've given up on them, agm will go 5 or more.
I doubt it's your ford's fault. Buy a $10 elm and download forscan so you have some empirical data on your alternator, testing with a dvm on startup doesn't tell you everything.

RE: "Newer" Ford trucks don't charge house batt's?
I found the brake thing to be true on my '15 350. I use an victron orion 12|12 9a dc-dc charger. It suits my needs for a small charge to keep up with the compressor fridge and utilizing the factory truck and camper wiring.

RE: Does anyone use an aftermarket Tire pressure system?
I have a tst507 on the truck and trailer. The sensors can be a bit of a challenge to get on and off the dually wheel(OP didn't specify). The flow throughs are too long for the truck wheel. I have the flow through on the trailer, although 1 now doesn't flow through very well~7yrs old. When I changed tires I ordered internal sensors, they were on back order forever and I gave up. I'd highly recommend that way on a drw although they are pretty spendy in total.
I like seeing the tire temps, I actually shifted some weight around since one front tire always ran ~10* hotter. I haven't had a blow out or flat with the system, just reminders to air back up.

RE: What did you do to your Camper Today?
Yes, also to clear the trailer tongue. It's a 992
I have a 992 as well. Are you not using a hitch extension?
I am, a 36".
I have a 24" for shorter tongues. my enclosed has a 5' tongue and the receiver is another ~10" so I don't use any extension.

RE: What did you do to your Camper Today?
Made some 4" lifts for the rear jacks.
I'm guessing this is so your rear jacks won't hit things when traveling off the beaten path.
Which model AF do you have?
Yes, also to clear the trailer tongue. It's a 992

So I bought two more and installed them today.
Have you noticed a reduction in the amount of dust on the back of the camper on dirt roads?

RE: Anyone made the dive to Lithium and had it in four seasons?
Exactly, with the exception if running a compressor refrigerator during inclement weather...
I put in a 110w dc-dc charger to keep up with my compressor fridge. I have been shutting the solar off on the drive home. It's worked out well with the battery drawn down to ~50-60% when we get back so I can just disconnect.

RE: Anyone made the dive to Lithium and had it in four seasons?
I think he means dc to dc charging. I have them, but in Phoenix we only have 2 seasons...maybe high 20s on a rare occasion. I insulated the battery compartment door so the batteries stay about the same as what I have the heat set to.

RE: Bigfoot tripping house GFI
Inductive loads cause ghost trips. Dedicated RV outlets are not GFCI protected, the outlets in the RV that need GFCI should be on there own. Heater elements and charge converters can do this, even though progressive dynamics says it 'should be ok'. I presume you have a gfci in the camper, so now you have 2 on the same circuit and that can also cause ghost trips. Our house is an old build and had a GCFI breaker, and later someone added one in the bathroom. The breaker tripped randomly, after the breaker was removed and the gfci placed correctly in the circuit it's been fine.

RE: Dometic Compressor Fridge Issue
You may want to try a small appliance repair shop prior to see if they can help. They are not complicated units, may just need an expansion valve.

RE: Why do I need a DC to DC charger?
On practical note for B2B charger is inverter combined with converter.
So if you already have converter adjusted for lithium, or whatever batteries and on-board truck inverter >>> you already have the system. All it takes is to learn how to use it.
To clarify - I am talking about 400W inverter Ford installs on newer trucks and potential for adding 1 on truck who doesn't have it.
400W inverters run for like 35 bucks.
I don’t think you’ll find a converter that’ll run on 400w.
I use a small Orion 110w dc-dc that covers my fridge draw at about 85w. Runs on the factory wiring so no need for jumper cables.

RE: 2013 Lance 1172 compatibility with Lithium ion batteries
the victron 712 has a contact that can be connected to the PD charger to disconnect at a programmable state of charge.

RE: Bigfoot tripping house GFI
Try unplugging your charge converter and see if it trips before you get to deep. I found it to be the issue with my other camper.

RE: Cooper tire failure at 65mph - now what?
Most people never go off-road. Most people never go off good dirt roads. That doesn't meant their trucks aren't capable of it.
Sometimes you get stuck. Sometimes you break stuff. Sometimes you have to walk out.
Hauling a truck camper or pulling a trailer just makes everything a lot harder. Just turning around can be a big problem.
Use some judgement out there. Buy good tires, watch your pressure and don't rock bashing without realizing the problems associated with mistreating tires.
AZ dirt roads are hard on tires, they are rocks with a little dirt in between. Everyone I know self included that camps up there has had an issue with every brand of tire.

RE: Rieco-Titan Electric Jacks Sticking and Not working well.
I recently took the gear heads apart on mine, cleaned out the 10yr old grease and reapplied a new layer, they are way quieter now. You’ll probably need to pull the head off the one that gets stuck, can’t help much there since I haven’t done that.
