RE: Comfort Ride Slipper Spring system w/shocks
Front slipper springs are about a $20,000 option over shackles and equalizer springs on the front of a twin steer 40k front Kenworth C500. They come with replaceable wear pads. Makes the truck more flexible off the flat road.
Back to regular programming.
I have an old diy flatbed made out of a tandem travel trailer chassis. It has slipper springs and equalizer, everything greaseable. It rides really nice, loaded or not.

RE: Damaged 5er hitch by backing too hard
I set the trailer height so there is a slight teeny bit of ramp up to avoid high hitching. I never lift an RV trailer ramping it with the truck. I take my time in and out of the cab as needed. They are too flimsy.
RoyF ‘s experience is good advice. Due to bad manners on the inter web most people would not share a story of a boo boo that caused damage.
Thanks RoyF

RE: Lifepo4 cold temp cut off 23F or 32F?
Some battery makers are now building self heating LiFeO4 batteries.
No they don’t use their own amp hours to heat. The batteries can deliver energy down to -20C battery temp.
They use energy from the charging source to warm the cells. Then they begin to charge.
Lithium batteries can accept charge at very high rates.
This is why a small generator or engine alternator charging is probably step one in a lithium system then do the solar spend to round out the system, especially if you camp in winter, forest, shade, or rainy lands.
I wonder how long the heater would take to warm the battery bank at -37 c?
Best possible charge rate for best cycle life is 0.2 c. A 0.5c works well, too. Yes, you can charge faster--but with a trade off in cycle life.
Battleborn batteries have a heated version--and it DOES draw from the battery to keep warm unless there is external power available.
If I were using them in a unit capable of -37C I would have them installed inside the heated envelope. If I had to let the unit freeze to ambient in storage at 25lbs each I would pick up the batteries and put them somewhere warm, partially charged, not needing any fussing with in storage, until I needed them again.
If you are where it gets cold, don’t buy self heaters that use their own energy would be a n option.
A guy could also use SiO2 batteries if actual cold exposure is common in the “mission”.

RE: Solar Rv awning -- does it pencil out?
I think the charts for my PD 60amp Converter charger with charge wizard says it takes X hours to bring wet cells to 80% SOC and 2 more days to 100%.
It’s why in my untrained mind wet cells and agm work so well with solar if the sun shines and fast charging batteries like lithium work well with fast sources of charge or Big Solar if the sun shines.

RE: Highway Thru Hell floods 2021
Like other questionable areas around the world, why would anyone in their right mind live at the bottom of a drained lake. Not the first time this has happened either.
its quite interesting, I was wondering the same thing and looked into the history. it was basicly a very very large, very shallow lake, more of a swamp, mosquitos and all that stuff. it was easy to build a "dam/spillway" from the sumas river to the fraser to divert the water and install a dyke and pump station to maintain it once they put the flow back to normal. the reason for doing it asind from getting rid of the "swamp" was that it would give them much needed rich farmland they despratly needed.
This was done in the 1920’s as a public works project. The Barrowtown pump station beside highway 1 lifts the water into the Vedder River whicj joins the Fraser.
The Fraser River flooded in a major way in 1948. This resulted in a major mitigation project.
There is lots of “tilted topography” north and east of the lower Fraser valley. It drains in a hurry. I’ve seen washing machine size rocks being rumbled down a creek that you can wade ankle deep in dry weather. It’s a noise you don’t forget when it wakes you up in your camper :E

RE: Question about Redarc 40A DC to DC charger wiring.
. . . DC DC probably has some control around overloading the alternator.
Especially REDARC equipment- Australia has been a decade or two ahead of north North America using on board charging equipment in campers and trucks operating in remote regions.Outside of input/output connections and a trigger input to turn the unit off and on, there are no other connections or sensors on a Renogy dc to dc charger that would relay any info about an alternator's condition, load or output rating. I've briefly read through the 25a/40a Redarc manual and I believe this is also true for the Redarc.
There are a number of ways to program the *output* of a dc to dc charger to protect and properly charge the battery; however, very few options (if any) to regulate the *input* load to protect the alternator (the only exception is the half-power mode on the Renogy).
This is why choosing a dc to dc charger with the proper current rating is important (in respect to alternator load).
I think otr is correct ^. I have a Renogy on the project shelf. It is a 40amp model. The literature states input amps are 60amps at 40amps output.
High output alternators are not super expensive if your oem one kicks the bucket..

RE: Highway Thru Hell floods 2021
Sumas Prairie south east of Abbotsford is a polder- a reclaimed lake bottom. When we lived in the lower mainland in the early 90’s we got 9” of rain in a day and a half courtesy of a “Pineapple Express”. There was a guy ferrying food with a motorboat following No. 3 Road.
This was all prior to The Climate Crisis.

RE: Question about Redarc 40A DC to DC charger wiring.
The starting battery between the alternator and DC-DC cushions the load on the alternator during the odd low output idle time one would think. This DC DC probably has some control around overloading the alternator.
Especially REDARC equipment- Australia has been a decade or two ahead of north North America using on board charging equipment in campers and trucks operating in remote regions.

RE: Solar Rv awning -- does it pencil out?
The Everlanders on you toob and the web doubled their panel capacity on a truck camper by using a slide system to deploy panels to the sides of the fixed set. They also shade the sides of the camper somewhat. They retract automatically if you forget when you go to move the truck.
The system uses conventional rigid panels and common rugged commercial parts.

RE: Question about Redarc 40A DC to DC charger wiring.
See if there is a tag or plate attached to the alternator frame somewhere. I would guess it is a Delco sumthin sumthin on your GM engine.
A good GM commercial vehicle dealership parts dept might be able to discover the original equipment alternator model from the engine number or chassis number build info.
Is there an original build line sheet deep in the file folder from Airstream?
