RE: Converter voltage drop
Hi Gdetrailer,
I agree. Li are FUSSY.
They can work well.
I'll never own them as I camp in extreme cold.

RE: Electrical question
And now you have people with electric vehicles plugging in which will make things worse.
Please provide a link that supports your opinion.

RE: Warm Fridge - Dometic DM2882
Typical in hot weather. Adding a fan that clips onto the fins inside the fridge helps.
Adding fans to the "chimney" also helps. My twin fans for the chimney are on a mechanical thermostat.

RE: Converter voltage drop
I'd go inverter/charger. Li follow the makers recommendations.

RE: Battery question???? XXXX UPDATE XXXXX
They need to be "Equalized" how to do that on your system I do not know. I know how I'd do it but it requires hooking them in parallel to a DIFFERENT charger.
Don’t equalize AGMs. It will damage them.
True statement. Everything I've read is that AGM's aren't supposed to be equalized.
Lifeline calls it "conditioning" charge. It is, defacto, an equalization charge.

RE: Where have all the members gone on this forum?
I try to be helpful. On one of my earliest posts, I wished the OP "good luck". He took GREAT offence.
Facebook is full of iffy advice.

RE: Electrical Help pls
Reflectix is for heat infiltration and isn't intended for cold. Details are on its packaging. So maybe find a better insulation material to put in its place and it could make a big difference!
Aerogel may be a solution.

RE: First big trip - Newbie questions
notsobigjoe,
5% more in fuel cost? I get about 11 mpg. But I drive slowly. (about 79 mph) If I drive 80 mph that drops to 10 mpg.
My GVW is 14500, so I'm well within the limits.

RE: Electrical Help pls
RickW,
I'm with you 1000% on CO. I won't run a non vented combustion heater--and I won't run a generator while sleeping, either.
My daughter is a CO survivor.

RE: Costco 100W 18V solar blanket: which controller to use?
profdant139 pwm controllers do not drop the voltage. They operate at what ever the battery voltage is. As the battery gets fuller the control "pulses" the power, with shorter "on" time and greater "off" time. PWM does include a one way diode to prevent the panels from drawing power from the battery bank.
110 amp-hour battery flooded? Then with this panel under PERFECT conditions 5.5 amps are going into the battery. But that only happens around solar noon.
I would be comfortable doing direct connection to the battery with an on/off switch between the panel and the bank.

RE: Electrical Help pls
Yes, I am bummed.
How many amp hours is the battery bank?
The rule of thumb is multiply amps by 10 to get the draw at 12 volts. This is due to inverters being at best about 88% efficient.
If the voltage on the battery is low, the inverter may well draw even more amps, causing the fuse to die.
Generally the inverter may be sized to do 125% of the load. 250 x 1.25 = 312.5 watts (so the inverter is busting its heart out trying to run that heater).
There are a couple of solutions.
1. connect the inverter directly to the battery posts. That will eliminate the fuse and amperage issues.
2. Use a 50 heating pad instead. You could run two.
3. There are 12 volt heaters available.
In any event the batteries are not going love running the heater for long periods of time.
My first battery bank was 875 amp-hours. Heaters were not an issue.

RE: First big trip - Newbie questions
Since water weighs 8.3 lbs a gallon, my full tank was around 500 lbs. I saved a few hundred lbs by not filing it all of the way up.
My weight with ALL tanks full (black, gray, fresh, propane, and fuel) is 13750 lb. That included two humans, with the RV provisioned for a 2 week trip.
Fresh water is 80 us gallons or 664 lbs. That's less than 5% of the total weight. Not enough to make a difference in fuel economy.

RE: First big trip - Newbie questions
Hi,
I travel with the fresh water tank full.
The savings from having partly full are negligible.
Partly full the water will slosh around. It may even act as a "captive hammer".

RE: You tube Fulltimers getting squeezed
Folks underestimate the costs. They don't have a reserve fund. I think mine is on the low side at 10 grand.
Some people are able to discipline themselves, and almost never stay in a commercial campground. Where I was full timing it may be nearly impossible from November to March. And due to covid there was no place to go south of the border. The only year round campground decided to become a seasonal site.
Fortunately I had an exit strategy in place.
My heart does go out to these new to RV people.
