1.1 Engine

1.1.1 Diesel vs Gas

  • Old common sense is that diesel more reliable than gas, may not still be so.
  • Diesel maintenance more, they hold more oil plus diesel exhaust fluid
  • Diesel runs at lower RPM, reducing wear on engine components.
  • Diesel has advantage when run hard over long periods of time, e.g. towing.
    • More Torque at lower RPM.
    • Exhaust breaking when towing for easier control
  • Gas more likely to have costly internal failures when hard over long periods.
  • Diesel has higher resale value
  • Diesel is more expensive upfront, as much as 10k.
  • Gas is superior for off road
    • Diesel heavier, no good for front heaviness in mud or sand.
    • Gas engines rev faster and redline higher - bigger effective RPM range, good for "desert running" and clearing mud from tires

If you live in a flat area like the midwest and you're not towing at 75%+ of limit of your 3/4-1 ton truck a gas engine will be more than adequate.

The new diesel trucks do not have the reliability of old diesels, many of these new trucks start having DPF and emission issues before 100k on the odo. And the MPG savings in the HD segment isn't a large as it once was, with these diesels choked down with emissions, a normal user would never save enough to pay for the upfront charge of the diesel. The light duty diesels get good mileage because they have zero power, they can barely get out of their own way.

1.3 Towing Capacity

source

In short, an average camper trailer weighs around 5,200 pounds (2,350 kilos) dry weight, which means the weight of the trailer when its tanks are not filled and it has no gear in it.

Expect another 1500 therefore 7,700 total.

1.3.1 Terms

  • Payload is the weight of all of the gear, passengers plus the tongue weight of the trailer, it does NOT include the weight of your vehicle.
  • Gross vehicle weight is the total weight of the car, passengers, gear, and fuel plus the tongue weight of an attached trailer.
  • Curb weight is the weight of the vehicle without any payload or passengers. Gross vehicle weight minus payload.
  • Combined gross vehicle weight is the total weight the manufacture has determined the vehicle can handle including the vehicle, all passengers, cargo, and fuel plus attached trailers.
  • Max trailer weight is the most amount of weight that a vehicle can tow.
  • Tongue weight is the amount of weight the tongue will put on the hitch.
  • Max tongue weight is the maximum amount of weight that can be put on the hitch and is included in the max payload. This may vary depending on the type of hitch being used. Example, it maybe 500 pounds for a weight bearing hitch and 1200 pounds for a weight distributing hitch.
  • Dry weight is how much the camper weights without adding any water, gas or gear.
  • Max trailer payload is the maximum amount of gear, water and gas that can be safely carried in the trailer. The dry weight plus the max trailer payload is the trailers gross vehicle weight.
  • Trailer Gross vehicle weight is the total weight of the trailer with all contents.

1.4 Clearance

1.5 Axle Ratio

The term refers to the gears in the truck's differential, which is a mechanical device that links the rear axle to the driveshaft and then the engine. Technically, the number should be expressed as a ratio, such as 3.55:1, meaning the drive shaft turns 3.55 times for each turn of a wheel. But that gear ratio would most commonly be referred to as "3.55" or simply "three fifty-five."

The key to understanding gear ratios is to remember that, as the numerical ratio goes up, towing capacity increases but fuel economy goes down. A numerically higher axle ratio provides a mechanical advantage to send more of the engine's available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump.

  • 6 ft harder to load lumber, etc.

  • 8 ft better to get work done

2 ft longer than my last truck really doesn't seem so bad considering the upsides of carrying an amazing camper or easily towing a fifth wheel.

Length considerations. 29 ft will allow camping most anywhere but 35 ft or less is recommended. Note that this is the total length of truck and RV. An F-150 Super Crew is 230" or 19 ft.

Truck Camper may the superior option if I go the custom route:

4 Final

4.1 General

My dream setup is living out of a camper. A four wheel pop camper (1.5 - 2k dry weight) or four seasons hard shell slide-in (closer to 2.5 - 3k dry) would be amazing.

Max payload F250 / 2500 class trucks is 3k, so this limits my options. F350 / 3500 series are marginally more expensive so they are my choice.

Chevrolet as smaller bed widths so they're out. Down to Ford F350 or Ram 3500. ^^ I don't think this is true, they are worth a look.

Hard requirements:

  • Gas V8 Engine
  • Max payload package, at least 4k.
    • Note: This will put the GVWR over 10k which means I'll need a Class E exemption if I title/license in NM
  • 8ft or 6.5 foot bed ???
  • 4x4
  • Camera(s) so I don't destroy things while parking.

Soft requirements:

  • 3.7ish rear axle ratio for better tow
  • Lane Assist warnings
  • Tow package

Nice to have:

  • Adaptive cruise control
  • Water sensing wipers

    • 10 brake applications
    • 11:53 @ 2.4 MPG
    • 48.5
  • Ford - 10 spd w/ Godzilla
    • 9 brake applications
    • 8:42 @ 2.2 MPG
    • 94.5 points
  • Ram - 8 spd w/ Hemi
    • 14 brake applications
    • Should manually downshift with trailer. Suspect of this transmission computer especially given was told to me at the dealership about the "flashes".
    • 10:29 @ 2.6 MPG. I would guess transmission tuned for efficiency.
