🏕️ F150 Tremor Camping Forum!

I range from 63 to 73, but mostly around the 67 mark. I was originally doing that for the tires and for range, but my wife got tired of sitting for too long so dont have to worry about range as much 😅
 
I was thinking about switching octane for the next trip to see if gas milage improves. I have heard of this before but didn't think to do it last year. I would love to get a few more mpg when going from michigan to Colorado or Utah.

The only thing I had heard about before re: octane with the 3.5L EcoBoost is that the advertised horsepower and torque numbers are with 91, but the engine can happily run on 87.

In truth, the greatest benefit is the engine not pulling timing when under load. When heading southbound just before Helena, Montana there’s a big hill. The ambient temp was 37˚C. The truck pulled timing about half way up the hill which then caused the engine coolant temps to start to rise despite having the Mishimoto radiator. I ended-up pulling over and letting the truck cool down. In hindsight that was not needed but it seemed like the safe and reasonable thing to do at the time.

Later on that trip once I had been running 91, there’s a big, long hill from Hope, B.C. up the Coquihalla Hwy. It was identical temps (+37˚C) and I only went into limp mode right as I crested the top. The nice thing about the oversized rad is how fast it can shed heat, so within 200m I was already back to full power.

So yeah, I’d say the fuel economy is somewhat of a bonus compared to the engine having more power and generating less heat. Don’t get me wrong, it’s a nice ($) bonus. lol

Sounds like you need a larger intercooler.

You’re 100% right. Please e-mail COBB Tuning with your support. Hahaha.

In all seriousness, I wrote them a proposal about a week ago asking for help with an intercooler that I can feature on my YouTube channel and talk about factory location front mount versus high mount features and benefits in the context of towing and hauling (think overland and camping).

With that said, I’m also in the research phase of thermostatically controlled auxiliary oil cooler systems, specifically how to size the cooler to prevent over-cooling in the winter but also large enough to manage pressure-drop and efficacy. I feel like for street cars, there’s a balance to be struck but there’s also a distinct lack of information for street applications. Most people adding them are sports cars for track use, but as we know, our turbos have oil feed and return lines and that heat is going to end-up in the coolant system.

I am running the cVF high mount currently, no complaints. They also have a factory location upgrade.

Oh, nice! Now, where did we land on you e-mailing COBB? Hahaha.

In all seriousness, do you do a lot of towing or drag racing?

We pull our Intech Sol Dusk with our 2025 Tremor. The trailer is small enough for towing long distances in a day and big enough to be comfortable at the destination. The only thing I wish it had is a couple of comfortable reclining chairs. The dinette area is ok, but not as comfortable as a recliner.
To improve load capacity and handling, I installed Timbrens and a Hellwig sway bar. Great improvement!

Finally got to try my setup out. Very happy with the results. The tent, the alu-cable with trail rax table slide, and a 10x10 canopy travel on the rack. When you get to camp, deploy canopy first (yay shade). Then pull the alu-cab table from under the rack so you have a place to land your crap, then deploy the tent. I'm down to about 15 minutes of setup. 20-25 minutes for teardown. I do also have the Annex for the tent. It's enormous and will only get deployed if I'm planning to stay put.

May want to take a look at these. We have 2 and had them now for 3+ years. Comfy and durable. No foot rest but high enough so getting out of it is easy. Tried the bungee lounges but so low i had to roll out of it and use my walking stick to help me up… https://a.co/d/09Qf7BPb

Very peaceful pictures!
 
We just got back from 4 months on the road exploring the NE this year. This combo has now been to 40 states.

Love our country and this truck!
