Any ideas where to install a third battery in a '24 2500 L5P that's not in the cab? Doesn't have to be huge, capacity/size are totally negotiable (ideally at least 10Ah), use case is a UHF/VHF amateur radio transceiver.

Why do you want a third battery for your VHF / UHF rig?

 

My 2016 and 2020 Diesels never had a problem with an Icom 5100 or a Kenwood TH-710G hooked up to the passenger side battery.

 

  I just bought my 24 3500 L5P a few weeks ago and I’m waiting for a little cooler weather to install a VHF / UHF rig.

 

  If you’re worried about the rig drawing down your batteries when the truck is off I would get a West Mountain Radio ISOPwr+ and a 10-20ah lifepo4 battery.  I have this setup in a battery box so I can take it anywhere.

 

  I mount the radio under the back seat and the control head on the dash.  The 24 dash doesn’t have the tray in the middle of the dash so I’ll need to come up with something different.

My preference is to have a dedicated battery for comms to not worry about depleting the truck's system. An ISOPwr+ (or similar) is definitely in the cards. For mounting the Bulletpoint Mounting Solutions RubiGrid has really piqued my interest.

 

I'd love to pick up another Kenwood TM-D710GA, have one in the shack that I could repurpose but I really hope I can find another one at a reasonable price.

I see your point about the comms battery.  Here in AZ vehicle batteries usually last 2 years or so.  A far cry from WI where they lasted a lot longer.  On the other hand I've never had to replace an exhaust since moving here.

 

I need to stay off these forums.  

 

Now I'll be ordering that RubiGrid after I get home these afternoon.

 

Good Luck finding another Kenwood mobile.  I'm hoping they come out with a replacement but the new HT hasn't shown up anywhere yet either.

Hah! Please let me know how the RubiGid goes. I'm holding off on ordering until I decide what to do about the radio itself, we're coming into the PNW hamfest season so there's a decent chance of me finding a D710. HRO in Portland has one NIB for $1k in their special display case off to the side, nope!

The RubiGrid doesn't fit the AT4 / Denali stacked dash so back to the drawing board for me...

 

Good Luck finding a D710.

 

I found one a couple of years ago that a local had won in a hamfest and didn't want to invest the time to learn how to operate.  I wouldn't pay over MRSP for a radio that may be replaced soon.

 

I have a pretty good Kenwood collection, TS480 (200 W), TS890, D710 and the D74 HT.

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By revmanii · Posted

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
