What is the new solution from Renogy? I don't see a link.

OP here. Thanks to all for your valuable input. As a consequence I have decided not to pursue a DC-DC charger at this time. Not charging from the alternator while driving has not been an issue to this point, and if I need to charge when the driving day ends I can always use shore power or genny.

I have installed three 12V 100AH LiFePO4 batteries. Initially I just disconnected the relay between the engine and house batteries to avoid the potential alternator issues of charging the lithium batteries while driving. I have solar, so depending upon available sunlight I might get by this way, but I am considering installing a DC-DC charger. What is everyone's favorite? I would just as soon not need to run a wire to the alternator if possible, simply replace the solenoid with the charger.

That would certainly make a difference!

Installing a fan--or propeller--backward does not reverse the flow. It may make it less efficient, however.

I thought I saw it in the owner's manual that came with the coach, but looked and can't find it. I checked the Cummins 5.9 ISB manual and it says to look on the engine dataplate. I will do that the next time I get the chance. I'm pretty sure I didn't just dream it....

The book says max boost on our 2002 5.9 ISB (built in 2001) is 22.5 psi, and I consistently see that or almost that at full throttle.

If it is anything like ours, the box just lifts out and provides access to the motor.

Thanks Michael. I think I will avoid using the boost.

I guess since the website for our new PowerUrus lithium batteries says "Our batteries cannot be used as starting batteries for cars", I should probably avoid using the battery booster switch....

I finally got around to crawling under the coach and checking how I disabled the solenoid valve, and I actually removed it physically and replaced it with a brass fitting that has a connection for a hose to extend to the side of the vehicle to connect to a gas grill.

Got it, thanks.

Thanks for that info, Bill. I will look into them.

Hey Ken, that is what I am hoping to find as well. What make and amp-hours are yours and how do you like them?

Thanks for the good info, Loel. Thanks Walter. Your experience before lithium was about what ours is now. So what kind of lithium batteries did you end up with, how many and what amp-hours, and how do you like them?

Thanks for the good info, Jerry. Given our usual usage, I am going to avoid the DC/DC charger issue by simply disabling the solenoid between the chassis and house batteries. We don't need to charge our house batteries with the alternator while driving. But what lithium batteries did you get, and how do you like them? Thanks.

Folks, I am researching replacing my 6v AGMs with lithium. The four AGMs produce 440 Ah, of which about 220 is usable. I would like to get at least 50% more usable, maybe 300 Ah minimum. I would like batteries approved for 100% discharge, or close to it. I would like high quality BMS with Bluetooth. Will Prowse seems to like the PowerUrus batteries (https://powerurus.com/products/powerurus-12v-100ah-lifepo4-deep-cycle-rechargeable-battery?aff=2). I could get three of them in my battery box. Any opinions on those or other currently respected batteries? Thanks. Jim

Sorry, maybe I misremembered, or maybe our system is different from yours. If your system is normally closed, obviously it wouldn't work to disconnect it.

We dry camp more often than not, and came to the same conclusion early on (we picked up our Knight from the factory in 2001). I believe I just disconnected the solenoid electrically; I didn't physically remove it.

They have renamed the "RV" service "Regional Roam," but it is the identical service.

I've always added oil through the oil cap on top of the valve cover. Much easier, in my opinion.

Thanks for the gauge info, Bob.

Hey Bob, That dash looks very familiar. We have a 2002 30' Knight, also original owner. They didn't make the 30-footers for long; guess they weren't very popular, but a lot of people ask about ours and want us to let them know when we decide to sell (not likely). I too added a couple of gauges to our dash: a transmission temp gauge on the right, and a voltmeter on the left. They were both from a 2002 Windsor, and match our other gauges. Can I ask where you got the air pressure gauge? I might like to add one of those too. Thanks.

I had an accumulator with my old ShurFlo variable speed pump, but when I replaced the pump with the Remco it made a lot of noise, I think when it was trying to shut off. I removed the accumulator and that cured the noise. But I am pretty sure the Remco speed is not varying; it just seems to cycle on and off. Could it be faulty or might there be another reason for that?

Hopefully it is just loss of prime. I am amazed at how tight the fuel filters have to be to prevent sucking air.
