    2020 Ford F250 on 37s - Expedition Truck Camper Build!

    True higher ratios are stronger. 4.30s are considered "thick cut" gears and sweet factory option! However, the strength difference between 4.56 and 4.88 is minimal (neither are thick cut). I wouldn't want to regear a 2nd time and having the flexibility for larger tires is great. MPG is...

    You unthread the air fitting from the diff cover. Thread in the "drive away lock" which engages the locker as you bolt it in. Really simple. Like 5 minute deal.

    2020 Ford F250 on 37s - Expedition Truck Camper Build!

    Thanks Zach - I agree. If I was paying to regear... It would be 4.88 all day long! But 40s would be short behind that. I agree, it's not worth the money for small gearing changes. However, with the 4.30 gears and 37s it seems perfectly happy. Recalibrated the speedo with (free) Forscan...

    37s Load D or E?

    Adding all the section ply counts together isn't how the ply count works. From Tire Rack "Today's load range/ply ratings do not count the actual number of body ply layers used to make up the tire's internal structure, but indicate an equivalent strength compared to early bias ply tires. Most...

    2020 Ford F250 on 37s - Expedition Truck Camper Build!

    I'm using the factory tire carrier. The Carli hitch is crazy expensive and only offers room for a 38" tire. I'm happy fitting the used 37" tire (close enough). I really doubt there is any MPG increase with lower gears. I monitor the real time mpg and every time I bump RPM by downshifting the...

    37s Load D or E?

    Ply count was how tires were made years ago... But nothing is 10ply today. They call it "equivalent" in strength based on whatever manufacturer standards. The tire world should be revamped. Same with the sizing. It's crazy you can buy a 37" tire and have the actual diameter vary over .5" or...

    2020 Northstar Liberty - Expedition Truck Camper Build!

    On this adventure we drive deep into Death Valley on the “less traveled” roads to explore the Hanaupah Canyon Trail. This is an off road type trail the gradually degrades until the path is lost completely from erosion. We started the trail late in the day and didn’t arrive at our camp until...

    37s Load D or E?

    We've been running 37x12.5R17 in load Range D with ~3,500 load capacity at 50psi. Run them in deep snow at 20psi. Off road @ 30-40psi. Keep the rear 5-10psi higher typically to match front sidewall deflection. Rear axle is about 6k lbs with the camper. I like running lower air pressure...

    jefe's hardside camper hauler

    Those stock springs are a rough ride!! Have Deaver Suspension build you a custom leaf pack. Then you'll have the load support and compliant ride plus flex. My replacement leaf pack had 10 leaf springs. Truck drops about 2" with camper load. So perfect factory rack when empty. Plus, ditch...

    2020 Northstar Liberty - Expedition Truck Camper Build!

    Our first truck camper was purchased brand new! 2016 Four Wheel Camper Hawk model and it was installed on a 2016 Toyota Tundra. The plan was for a more comfortable “overland” adventure vehicle for week or two week long expedition off road trips. With the ability to remove the camper and have...

    2020 Ford F250 on 37s - Expedition Truck Camper Build!

    You don't need to drop the radius arm mount for ~3" lift. You will need proper caster shims to get alignment (I believe the shop installed 2.7 or 2.9 degree shims). We had the factory sway bar and purchased the Carli end links. Carli guys didn't realize that the sway bar position changed for...

    2020 Northstar Liberty - Expedition Truck Camper Build!

    Yep. The crazy thing is... the platform bolted up directly to the extended cab. Bikes still fit! It looked feasible from the measurements but much tighter. Absolutely love the shorter 148" wheelbase. That extra 12" in wheelbase is rather noticeable.

    2020 Ford F250 on 37s - Expedition Truck Camper Build!

    For 2020 Ford removed the optional "manual shift" transfercase lever. It was available in the current generation from 2017-2019. I'm sure the lever could be retrofitted but the electronic 4wd actuator has been working well and not many failures reported. The Dana60 has automated/manual hubs...

    2020 Ford F250 on 37s - Expedition Truck Camper Build!

    It is very predictable. It has no issues in the corners or with sway. However, I wouldn't recommend removing the sway bar with the stock suspension. Sway bars help on road in the corners to limit sway and slow weight transfer. But most don't realize it works against you in most other...

    2020 Ford F250 on 37s - Expedition Truck Camper Build!

    How much can custom leaf springs improve the ride? A TON! I’ve had custom leaf spring packs designed for the past four truck builds. Properly designed springs not only provide the “lift height” desired, custom load capacity but also performance. Stock leaf springs were not designed for high...

    2020 Ford F250 on 37s - Expedition Truck Camper Build!

    We used a fleet manager to custom order our 2020. It was nearly the same price as the used trucks... We removed the front sway bar. It rides much better especially off road.

    So… What is the difference?? Body = Same (except badging) Interior = Same Frame = Same Front Axle = Same Rear Axle = 2017-2019 F250 & F350 Gas (not HD tow) : Sterling 10.5” 2017-2020 F250 & F350 Diesel : Dana M275 10.8” 2020 F250 6.2L : Sterling 10.5” 2020 F250 & F350 7.3L : Dana M275 10.8”...

    2020 Northstar Liberty - Expedition Truck Camper Build!

    We have the camper installed currently... Headed to Death Valley next week. So no pictures. Video shows the guides. They are 1/4" aluminum L channel welded to the bed (which is also aluminum).
