RE: DC Power Issue
.
.
.
With shore power disconnected: battery shows 12.9V and DC fuse panel is 12.6 V.
With shore power connected: battery shows 14.6V and DC fuse panel is 13.6 V.
With shore power disconnected and solar panels uncovered in full light: battery shows 14.5V
So I conclude wiring from solar panels to battery is ok and wiring from battery to DC fuse panel is ok.
I disagree ! There should be ZERO voltage difference (drop) between the battery and the fuse panel.

RE: new generator time
We need to replace a 5000 watt, 2 phase, ...
No such thing as a "2 phase". Likely it is a 240V split phase. Yes, it has two 120V "legs".

RE: Converted to Lithium-Ion be careful.
There is no evidence that lithium batteries caused or were a part of that fire. What a bad headline.
Very true !
The article doesn't mention lithium battery chemistries although the types of equipment used would indicate they are not LifePO4 which is heavy and bulky compared to other lithium batteries commonly found in the types of electronics described in the article.
The chemistry used in the RV industry is typically Lithium iron phosphate which is very stable and has a very low risk of fire. Between lithium battery chemistries there are different levels of safety and handling perimeters.
Some DIYers are building "power walls" out of used lithium cobalt (the most common lithium battery chemistry because of it high power to weight ratio 18650 battery cells because they can get them cheap. Cell quality, charging and discharging rates, balancing and temperature monitoring are CRITICAL in these applications. I would stay away from these except in small sizes, (cell phones, laptops and power tools).

RE: Radiator performance? Life expectancy?
I don't recall this ever being an issue in the past.
Not a good sign ! If you did not swap it ahead of your trip, I would carry a spare (OEM).
I'm wondering what I should expect from my radiator. It is original and has never been touched, flushed or anything.
So you have the original coolant in it ! That would make me nervous also. Dexcool turns to sludge if it gets too hot. Really hard to clean out.
I do all of my own maintenance including radiator "flush". Drain, fill with fresh water and Prestone Flush chemical. Drive for at least 30 minute. Drain, refill with fresh water, drive for 30 minutes. Drain and refill a second time and a third 30 minute drive. Drain, fill with coolant.
The problem is, it is pretty much impossible to drain all the old coolant/water out of your system which is why I do TWO fresh water rinses. When putting new coolant in, I use 100% non-diluted. Use your favorite procedure to remove air. Check the strength. Adjust with water or coolant to meet the strength requirements.

RE: aluminum f150 body work
no fault insurance in Ontario. welcome to government sanctioned robbery. getting insurance involved would hurt me more than just spending my own hard earned money regardless of the fact that I did nothing wrong......
MI has had "no fault" for many years. I had to use it a couple of years ago. The insurance company waved my deductible because the other person was at fault.
First claim I have had with any insurance company in over 30 years, so there was no big increase in semi-annual price.

RE: NEC 2020 & Receptacles
Interesting ! There is actually an exception in the NEC for refrigerators on concrete floors (basement/garage). No GFCI is required if it is a dedicated circuit and a single (not duplex) outlet.
RV stores are going to start selling "No A/C power" alarms !

RE: Delam or not to delam
If you do have delamination the real issues are what caused it (likely a roof leak) and did water cause any of the structure/sheathing to rot/mold.

RE: 6 Volt RV batteries
Compare the specs of a T105 with a Interstate GC2 (Costco) or a Duracell GC2 (Sams). IIRC, you are only giving up about 10% of the capacity.

RE: 2 6v batters VS 2 12v
Trojan isn’t a distributor or retailer, wizard. The T1275 is a true deep cycle 12 volt battery.
100% correct !
Where do you buy them and how much do the cost ?

RE: Residential refrigerators
It works fine on the existing, but can I expect longer range problems with the old inverter, or should I “bite the bullet” and spring for a pure sine wave inverter ?
Electric motors (including the compressor inside your refrigerator) run more efficiently and cooler on a PSW inverter.

RE: 2 6v batters VS 2 12v
Mostly because 2 large six volt batteries in series gives you more amp-hours than the 12 V batteries do. For example Our 6V Interstates have a rating of 220 AH (amp/hour) each where a 12V might give 80-90 AH each for a total of only 160-180 AH (example). Plus the deep cycle battery handles deep discharge and recharge better.
Despite what the distributors and retail establishments tell you, marine/dual purpose 12V batteries are NOT true deep cycle batteries. The only commonly available TRUE deep cycle batteries are 6V golf cart batteries.
(12V deep cycle batteries DO EXIST, but they are hard to locate (typically special order) and very expensive)

RE: Ford Questions
Don't know about hub caps but tow mode just keeps it out of overdrive and decreases fuel mileage.
It depends on the exact model of transmission. Older (4 speed) transmission did exactly as described. Newer (5 and 6 speed) change when shifting occurs (typically earlier) and may inhibit OD in some cases.
The decrease in fuel economy is because you have more power at the rear wheels.
With my old E150, I left it in OD, but turned that off when approaching hills.

RE: 12 inch wheels/tires
Blowing smoke ! Nothing wrong with good quality tires as long as you are not exceeding the load capacity and are keeping them properly inflated.
The smaller the wheel and tire, the faster it spins. The faster it spins, the more important good lubrication is. Every time you fuel up, check the temp of the bearing/hub. If you are spitting lube or you can not put your hand on it for more than a second, it is time to re-lube/replace the bearing.
An extra 2 sets of bearings are cheap insurance. Tools/grease to do the job are cheap insurance. A second (even unmounted) spare is also cheap insurance.
eTrailer does not sell "junk". Call them.

RE: Heading to the Rockies for 5 or 6 weeks.
We know that we may have to bug out of some areas due to snow ...
Personally, I would do just the opposite ! Make sure you have enough food and fuel to stay a couple of extra days. This time of year, any snow might melt in a couple of days.

RE: replacing plywood roof
If you are into a restoration that deep, use marine grade plywood & give that a coating of an additional preservative so that you will never be doing the job again.
Real marine grade plywood is incredibly expensive ! (Hint: You will know it it the "real thing" if it is sold in mm thickness and NOT inches !) 1/4-3/8 ACX or BCX is more than adequate for the job.
Any additional coating should NOT be required if the roofing material is doing its job !

Generac GP3000i/Craftsman CMXGIAC3000 Inverter Generators
These two inverter generators appear to be clones, except for the color. The Generac uses their typical orange and black and the Craftsman is red and black.
http://www.generac.com/GeneracCorporate/media/Library/content/all-products/portable-recreational-power/GP%20Series/GP3000i-HERO.png?ext=.png height=350 width=550 https://craftsman-brand-production.s3.amazonaws.com/spree/images/3807968/original/CMXGIAC3000_2.JPG height=350 width=350
A couple nice features I have notice are
a standard 120V receptacle AND a twist lock 120V 30A (NO TT-30) they claim to be 2300W continuous and 300W peak
The only place I could find the Craftsman version was on eBay, and the price was around $500.
Any "real world" experience with either ? Can they really do 2300W continuous ?
