Normally changing the GVWR requires a manufacturer that's DOT recognized. It's not something you can do randomly as a mechanic or engineer. The OEM is of course the first and usually the only one that can do it but it's done by upfitters or limo builders. In those cases the GVWR may not be...

Is this a new knife or an old one?

Cell providers do prioritize bandwidth, but it's not an easy solution. Suffice to say that if you're using cell data it's best to be a regular subscriber on the company's network, e.g. be a Verizon post-paid unlimited user on a Verizon tower. The carriers also will move users up and down in...

GPX wouldn't be the way to get this into Google Earth. You'll need a KML or KMZ and the USFS wants you do get that though the USFS ArcGIS Geospatial hub. Use the KML option here, one for roads and one for trails: https://data-usfs.hub.arcgis.com/explore?query=mvum This will just give you...

FYI, it's only double cab trucks that had these captured nuts. You didn't say what you have. I'm not 100% sure all double cabs do, either. I just know regular and access cab do not. The nuts are standard Toyota (e.g. JIS) M6-1.0 size and pitch. Lengths will depend...

BTW, something that came to mind in the constant search for greener pastures. Selling a 2006 to get a 2012+ opens you to the secondary air pump failure. Which may be covered under a recall but only if yours has a check engine light on for it. If the valve or pump, whatever it is, fails it can...

The head gasket issues are said to be build dates prior to November or December 2005. But that's based on somewhat anecdotal evidence. One is a poll on TacomaWorld, which is statistically pretty meaningless. A somewhat more compelling argument is part number 11116-31011 shows an effective...

Just one small addendum to @86scotty's excellent info. First is that it's true that most use the Secop/Danfoss and in that regard the significant difference is if it's an actual Danfoss or a copy. If it's a legitimate one such as the major brands will use then the difference in performance...

As KC3NSR mentions for simple and rugged it's hard to beat plain old 1/4λ mounted on the roof. I've always had good luck with the STI-CO Flexi-whips. These aren't cheap but if you look closely to the antennas they mount on wildland fire trucks and that sort of thing these are what you'd find...

Wow, that's a lot different. I've only ever owned this MT45, 16 years now, so I thought they were all worked about the same. Mine probably runs 10 or 15 times an hour, high duty cycle but fairly short periods.

I have small packs that do this and it's annoying. The problem is what they sense as activity is just enough more than a few loads I want to keep constantly powered. But the design intention for those little portable packs is to charge a phone or tablet that would consume on the order of 12W...

The system is an extension of Inmarsat ELERA used for IoT devices. The underlying technology is driven by MediaTek and the 3GPP 5G NTN initiative (3rd generation partnership project 5G non-terrestrial network). It's different from Inmarsat phones but is an existing system intended for short...

Gel and AGM are both considered non-spillable so safe in aircraft cabins, so either should be fine in a vehicle cabin. The thing to watch charging lead acid is the chance of outgassing hydrogen if you push one too hard. In a well sealed cabin there’s is a very small explosion risk that’s...

The Goalzero thing just makes a connection to each available output, so there's not really a high current output per se. It could be fine to rig up something similar with other portable power sources in theory. Each output would only add what it's designed to do and provide that to the...

This seems like a question you need to answer for yourself. I'll say that I've found high current connection to a portable battery useful. For example giving the option to use a faster charger, in my case a 45 amp. On another battery I had an Andersen SB175 connector that I was using for a...

The Bluesea 1045 can do 2.4A per USB port, so it is indeed a 12W charger. It can do a total of 4.8A for both ports. If you want to stick with this form factor there are other options that can provide higher current. AFAIK the iPad 12.9 Pro comes with a 20W USB-C charger. The battery is...

Absolutely true that it's important batteries put into banks be closely matched in type, age, condition when you're discharging. This is basically mandatory if you want the batteries to last without accelerated aging. Understand that batteries have different characteristics when they are the...

@Herbie, greater than 27V input I think came from a nominal 24V controller document so the assumption is simply that the engine is running and charging. I don't know for a fact that all Secop/Danfoss/etc work this way or use these same values. Clearly the Secop design intent in this case is to...

How those Secop/Danfoss controllers work for sure is not something I've ever figured out. They're pretty tight-lipped about service manuals via web searches. I've got some design experience in similar products so it's not esoteric per se but I've just never seen schematics nor have had one to...

Interesting point about insulating. Would point out that it's the first layer on the drum that's the one that is exposed to the most heat from the motor and brake. So the operator should be thinking of heat everywhere in the system...
