Interesting comment. I tried searching this forum before posting initially but found very little on the subject which is why I posted in the first place. I’m curious why you state it was “dismissed as not feasible”. Seems totally feasible to me if a aftermarket company offers a larger fuel tank for the same truck which is diesel powered and whose numbers are a fraction of the gas powered counterparts…. What am I missing Bikerjon? Who wouldn’t want the ability to go 600+ miles between fuel stops as opposed 380 or so?

Leave it to the Aussies! Too bad shipping would be an issue to those of us in the U.S. https://longrangeautomotive.com.au/Chevrolet-Silverado-1500-Petrol-Dual-Cab-190L-Replacement~25665#UORe0njfdRgu1aP9RxNV19wMTAxMTE

So, if that were true, that would mean that there is a large enough market for Titan to offer an oversized diesel tank for these trucks sold with a diesel engine, but not large enough to offer a gas version for the same truck…. According to DOT sales figures, only 13% of light truck sales are diesel, so I think something else is at play here.

24 ga is simply too small. I heard from an engineer that this was to keep weight down on the vehicle to maximize fuel efficiency during EPA testing. It’s no secret that OEMs are putting options on vehicles such as start/stop, cylinder deactivation, E-assist, turbo 4 cylinders, etc for one purpose only. It’s so they can be driven in a manner that no one in the real world drives like to maximize the EPA test results. I still don’t understand why any “optional” or aftermarket companies are not designing gas tanks that can provide customers with the ability to minimize their need for fill ups…. I thought the diesel tank “retrofit” would be a popular work around.

I’m looking at the possibility of replacing the puny 24 gallon fuel tank on my ‘21 Silverado crew cab. I think GM really missed the mark when they decided on this size tank as the only option. I understand this is an EPA-based decision, but Ford and Ram both offer extended tanks as an option. I’m tired of filling so frequently . The only solution I can come up with is to buy an aftermarket diesel tank (offered in 43 ga capacity) and swap out the factory tank. Anyone had any experience in such a mod or have any suggestions??

Thanks for this info and photos!! I can’t believe that GM puts such crappy sound systems in a $60K vehicle and that it costs north of $1K to “fix” it. I contacted Crutchfield initially, but I think the kicker solution might be better for me as it is matched to the truck.

I stand corrected. I was ignorant of the fact that the sensor technology is not simply wholly encapsulated within the side view mirrors. (Perhaps others are also unaware that this is not a simple function of the mirrors alone and is much more complex) After a more thorough investigation, blind spot detection utilizes sensors (and electronics) located outside of the side view mirrors and the indicator light in the mirror is simply for driver feedback. Goshers offers (or offered) an aftermarket kit, but it appears that installing the sensors pointing in the exact correct location is critical. Brandmotion also offers a kit at $799.95 which in my opinion is a bit pricey. So bottom line is that this is not a simple mirror replacement bolt on thing. (I was naive!) It’s much more complicated than that. I learned a lesson. Hopefully this will help others as well. Looks like the best approach is to buy a vehicle with this tech included from the factory or use a convex mirror add on if your side view mirrors don’t already have them. Sorry for the confusion on my part.

What kind of a GM Truck site is this? This is the best advice it provides for this guy who wants to upgrade his side view mirrors to have blind spot monitoring? There must be a way to do this that is affordable from a donor junkyard vehicle with this option.
