The best thing you can do for mpg’s is have a daily driver.
Between my truck, daily #1 and daily #2 I average About 30 mpg.

Don't overthink this. I don't believe added weight has that much effect on fuel mileage even if Google says so. Aerodynamics matters. How you drive matters. Adding aftermarket bumpers, roof racks, and winches may throw off aerodynamics. But you've got to add a LOT more than 100 lbs to see any decrease in fuel mileage. I've made multiple long road trips in my Tacoma and other vehicles. Some were with just me and my wife and a small amount of cargo. Others involved us, and 1 or 2 other passengers along with enough camping/hunting gear to cause the truck to sit low in the rear.

On trips where we were taking in the sights and driving at, or under the speed limit fuel mileage was great. On other trips, (usually hunting trips), where time constraints made getting to Colorado and back home in a hurry meant driving as fast as I felt I could get away with meant fuel mileage suffered.

In 2016 we took my wife's sister with us to the Grand Canyon from GA. From there we hit most of the NP's in Southern Utah before coming home through Colorado. We were loaded heavy along with an extra person. With the 180 lb cap on my truck along with camping gear we were probably pretty close to maxing out payload. With 3 people and everything else I had an extra 1000 lbs on the truck.

The average fuel mileage for the entire trip was just over 20 mpg. Off the interstates in NW Arizona and SW Utah where speeds were around 60 mph and the terrain just hilly enough to allow lots of downhill coasting I got 22-23 mpg on a couple of tanks. On the way home we hit a steady headwind in Denver that didn't let up until Kansas City. I only got 16 mpg on 2-3 tanks. Other than those 2 extremes I was pretty steady at 20 mpg on every other tank. Which is actually a little better than I normally get on shorter drives on the highway even running empty.

I thank you for the feed-back/info. It's all relative. Good luck w/your CO hunts. Big season for that here in north NM, many elk and many elk hunters

I'm about to add some weight to the truck.
At 18 MPG w/300 added lbs., at 2% reduction per 100lbs, = 16.92 MPG.
Not bad, right? The approx. 110lbs front bumper and 124lbs skids I'm going to put on won't get me into that bracket of 6%/300lbs added range, but the sliders and rear bumper surely will and then some.
I'm just curious, does this seem accurate to others?

Northern New Mexico!
I’m planning a trip there in 3 weeks to escape the smoke in Northern Ca.
I was going to Oregon but that’s not working out.

Nice. Keep in mind hunting season is on of course, and also cold/snow at higher elevations. We got slammed here w/half a foot to foot already

Yeah, weather wise I figured I'll wait and see what happens.

I didn't think about hunting season at all..thanks for the heads up.

No problem. Bring some warm clothes, maybe some orange. I'm gonna pick up one of those bright reflective vests to keep in my truck kit. You planning on around Taos area?

I think so. I believe the guy I’m going with has friends that live in or near Taos.

I’m pretty excited. I’ve driven through NM a few times with stops at White Sands missle range, Carlsbad caverns and Albuquerque.
So, I haven’t seen much. Looking forward to seeing more.

Right on, northern NM is nice. And if it gets cold you can just go south some, though at night it can be cold in the south as well. I'm from Taos and live north of there on the NM/CO border. Right now bow hunters are lurking around my house in the adjacent ag. fields. If you guys need any tips on the area, lemme know, though it sounds like you got a handle on it. I like Albuq., and Carlsbad, never been to White Sands. Some good rockhounding down there. That's what I'm primarily doing in my truck, mineral exploration

I very much appreciate the information, notes taken. I'm like you, I drive slow. Especially at night. We are f'n inundated by elk here in northern NM, hence the ARB front bumper soon. I see what you mean about the 2% being way low. That's bad-ass you're mechanic and can do all that work on your rig yourself.

its all depends, I have DV8 hybrid bumper its about 200lb. I have not decreased mpg. Till I add pro exhaust. (Intake already install before the bumper).
