RE: DC to DC charger
What I have not seen posted is the fact that even if you use like chemistry batteries in the camper and truck, the capacity and age of the different batteries also affects charging (in addition to the small gauge trailer plug wiring). When you look at the diesels with dual start batteries, they have to be changed out in matched sets to keep optimal charging and power delivery (discharging). Putting in a DC to DC charger helps overcome these differences.
My two lifePO4 (560ah) will charge at 50 amps until they are almost completely charged with the low internal resistance unlike lead acid or agm.

RE: DC to DC charger
I just use a pair of 8 gauge wires from the truck battery to the camper batteries. That eliminates the voltage drop of the 7 pin and puts a nice charge into the camper batteries whenever I drive. I use a 200 amp blade switch that is mounted on the truck battery to isolate the truck battery when the situation calls for it, but that is rare.
The reason it’s working for you , and also for me , is the age of the truck . Newer trucks , last decade , have smart charging , meaning as soon as the starting batteries are satisfied charging goes way down , so the house batteries would get very little , especially with the voltage drop.
That is not true on newer GM HD trucks, my 2019 Chevy 2500HD sits above 14 volts, when changing my batteries it will ramp up to just above 15 volts @ 50amps.
According to the above statement I should have a smart alternator, but I have yet to see this mysterious lowering of voltage a few people on here keep stating. So maybe Ford and Ram do but my 2013 and 2019 Chevys don’t or if they do the alternator is smart enough to ramp up under heavy load.

RE: CAT 3126E acceleration power loss after fuel filter change
Could something have gotten on your MAF sensor when you changed the air filter?

RE: Aqua-Hot in Cold Weather - Issues with Performance?
It could be as simple as improperly set combustion, when everything was changed was the burner combustion checked? Is it only in the cold when it fails and what altitude were you at?

RE: Honda 2000 won’t run my late model home furnace
Has nothing to do with the fuel source, .Has everything to do with the fuel if it's electric.
Furnace implies it burns fuel. Otherwise it would be an electric heater and 2000w is no where close to enough for a whole house electric heating system.
As others have mentioned, it's nothing to do with the sine wave but with the grounding.
Could be oil fired, they draw more power for the burner.
