On the highway my 6.2 gets over 20 mpg. Better than my 2016 5.3. For a lot of long distance driving I'd consider the 3.0. Driving short distances and never letting an engine warm up is much harder on a diesel than a gasser, but that doesn't appear to be an issue with you.

I'm not aware of the app letting you learn only one tire, so my guess is that's you'd just have to relearn the three older tires and learn the new tire. Just follow the normal relearn sequence. No need to delete and re-add your trailer.

Mine also had the 4.3. But I don't remember any real vibration problems. Good little truck. Only failed me once when the coil pack went bad. Mine was a two-tone blue over silver color with blue interior.

Damn! I had a 1989 GMC S-15 that I had for 12 years. It had 111,000 miles on it when I sold it in 2001. Replaced it with a 2001 GMC Sierra that I sold in 2015.

No. The trailer TPMS sensor is totally different from the one in the truck's tires.

I tow and that is too much trailer for too little truck. A trailer that size is firmly in 3/4 ton territory. I'm sure plenty of people will say that they tow even more, but the bottom line is it's too big and heavy. You'll more than likely exceed the max hitch weight of 960 lbs. The 680 lb tongue weight is based on the trailer's empty weight from the factory. Add in propane, batteries and all your supplies and it's going to be much higher. My 5.3 would struggle in the mountains with a 5500 lb trailer. I can't imagine towing your trailer with a 5.3. But if you're only going 100 miles and it's fairly level you'll probably get by.

My 2016 came with two "free" oil changes and my 2019 came with one. I refuse to let the dealer touch my truck for anything other than recalls, so I never let them do any of the "free" oil changes. I do my own.

Never looked for one. I just use a Mobil 1 M1-212A.

No adaptor needed for my 5.3 or my 6.2. Fumoto still the better deal.

GM recommends premium, so I run premium. I'm not skimping out just to save a few pennies.

So after all that, I'm still not seeing anything that would have me switch over to ValvoMax. From a bean counter's perspective the Fumoto is the better value.

You can ask all the rhetorical questions you want, but I'm still not seeing one single advantage that a much more expensive setup like the ValvoMax offers over the Fumoto on the Silverado/Sierra. You still need to deal with the oil filter and all the oil that drains out with it. So what's the advantage of their oil bag? I don't blame ValvoMax for not addressing the oil filter issue in their video, although it is a bit disingenuous to do so. Most DIY people already have everything they need to do an oil change. The Fumoto and the ValvoMax just simplify the job and make it faster and less messy. But the Fumoto is less expensive and less complicated and has a proven track record. I'm all about new technology, but it has to offer me some kind of benefit. And the ValvoMax offers nothing over the Fumoto.

I'm trying to come up with one advantage this has over a Fumoto for Silverado/Sierra applications. The video totally overlooks the fact that you have to change the oil filter too, so their little oil collection bag is useless for that. And that flimsy paper funnel is a joke. The Fumoto does not require a detachable hose fitting that can get lost or misplaced or forgotten on a road trip. Sure, you can just remove the valve, but now you're back to a messy oil change, and you'll need a new crush washer when reinstalling. With the Fumoto, you can drain your oil anywhere, anytime by simply turning the spring-loaded lever a quarter turn. Valvomax is a solution in search of a problem that was already solved by Fumoto in a much simpler and less expensive way.

No mention of how you change out the oil filter. Oh yeah, you still need an oil drain pan after all. And that flimsy paper funnel. What a joke. I anchor my oil funnel to the windshield wiper with one of those tiny bungee cords I thought I'd never use. That way it doesn't move around as I'm pouring from a five quart jug. Valvomax may look appealing...until you actually use it.

Something that size shouldn't give you any sway issues, as long as you have enough weight on the tongue, which shouldn't be an issue once you have propane and a battery on board. My trailer is a little heavier and I have no sway issues. In fact, I don't even use the sway bar that came with it, because the trailer is so rock steady. The only thing I did was replace the cheap China bomb tires on the trailer with Goodyear Endurance tires. I would recommend you do the same, as having a blowout on a freeway or in the middle of nowhere is no fun. I found that out the hard way, as have many others.

Silverados have built in trailer sway control. If you have a sway issue, you most likely have too little truck and too much trailer. Other issues could be too little weight on the tongue or cheap trailer tires with too much sidewall flex. But the most common issue is too little truck pulling too much trailer.

They come in sets of two at $125 at the dealership. There should be lots of them around from private sources, as most people don't even tow. And no, mine are not available. I used all four on my travel trailer.

It might be somebody didn't know what they were doing and they ruined your sensor.

I would like to add...get the one with a nipple. That way you can attach a length of clear vinyl tubing that reaches the oil drain container. Otherwise it will splatter, just like it does when you remove a drain plug.

It could interfere with vehicles that have radar cruise control, which has the radar sensor in the front of the vehicle, in the grill area. GM uses a camera mounted up in the windshield, by the rear-view mirror. If it's below the hood line, no worries. Above, you'll have to try it and see.

Trip back to the dealer. Should not be lighting up unless there is traffic in your blind spot.

Ford absolutely nailed it with their 12 inch landscape-oriented screen. I wish GM would do the same.

I've been using Fumoto drain valves in a variety of vehicles for decades now and I've never had a single issue, whether during Alaska winters or Arizona summers. I don't off-road my truck, so I can't speak about clearance issues. My Jeep is armor-plated underneath, so the Fumoto is well protected. I would cover with a skid plate if doing any serious off-roading.

My 2016 came with 3.42 axle. 5.3, 6 speed, no max tow, 20" wheels. My 2019 also came with the 3.42 axle, but it's got the 6.2, max trailering package and 18" wheels..

That's all I ever use on any vehicle with a canister filter.
