Gas TV for a year long trip

Hello everyone,

My wife and I are considering doing a year long RV trip with our two kids, that would cover the entire continental US and a trip up to Alaska at some point. We've decided we want a 5th wheel and are leaning towards the Jayco 29.5FBDS with a 10.5k GVWR. I am looking at F350's either with the 6.2L or the 6.7 diesel.

I am aware of all the pros and cons of gas vs diesel, I used to own a 2000 F350 dually and currently have a 2017 Tundra. My main concerns are range with the gas engine, the length of time we will be on the road, and towing in the mountains.

I think the range issue could be solved by adding a transfer tank into the bed of the truck. I would love to hear any feedback from people who have gone this route. I know that gas fuel tanks cannot be gravity feed from an auxiliary tank, but I'm ok with pulling off and topping off quickly.

The length of time on the road and towing in the mountains issue I would love to hear some advice or feedback of people who have done what we are thinking about with a gas engine.

There are some other issues which are impacting my decision. After the year of travel is up, our plan is to return to our land and get building our house to start our homestead. The truck will then become our work truck around the farm in addition to our RV tow vehicle. I like the gas engine for this, I can see a lot more starting and stopping and short trips and diesels don't like that a lot.

The other issue pointing me towards the gas is that for me to get a 6.7L diesel, I will have the cost of deleting it. It's not a huge deal but it's an added 1.5k-2k expense on top of an already more expensive truck.

Also, I'm looking at used trucks somewhere between 2012-2016 and less that 75k miles.

Thanks for taking the time to read this and I greatly appreciate any advice/criticisms anyone might have.

Tony

  • Not sure why you think you have to delete the emissions on the Power Stroke, unless that's something you just want to do. The emissions on these trucks have been pretty good. I have 172k miles on mine and I've been very satisfied and add DEF every oil change.

    If going gas I would give a hard look at the new Super Duty's coming out later this year with the 7.3 gas engine.
  • Sounds like you've already made up your mind and covered all your rational and excuses. Just do it now. I don't think anything anyone says will change your mind. Do-able, yes.
  • I've towed (race car) trailers gas and diesel for 25 years and all over the country. Personally, I wouldn't even consider a trip the miles and duration you're talking about without a diesel. The reasons are almost too numerous to list. Good luck whichever way you choose, sounds like one heck of an adventure.
  • I've got a 91 gallon tank for diesel in the bed of my truck. Add that to the 36 gallons the truck came with and I can tow my 19,000 pound trailer over 800 miles before needing to refuel. The real benefit is I choose when to refuel and that is always without the trailer in tow.

    Back in 2009 I was towing a 24ft boat with a Ford gas truck with the 7.5 liter gas engine. It really sucked towing the 6% grades going to the lake. Borrowed a friends Duramax and was able to tow at the speed limit with the cruise on. That was unheard of with my truck. I bought my own Duramax and haven't looked back.
