Wow, thank you for all the good advice, I'll try to address each point.
First, yes, the Camry is paid off lol. I paid cash for it a year and a half ago. I actually bought it as a 2nd vehicle for my gf, but we both work together and ride together, so it rarely gets driven.
My commute honestly changes job to job. We moved into an apartment for the winter while getting some repairs on the trailer, plus northern winters are pretty cold, and that was a 25 mile round trip. Now we are in the trailer and less than 5 miles away. Next month we are moving down south, which will be about a 1200 mile drive, and unsure what the commute will be yet.
I have 52,000 miles on my truck, and it's just over 2 years old, so needless to say, I drive a lot. Often biking is not an option. I work on a construction site, have a lot of stuff to bring with me, and often the drive is single lane busy highways.
When I move, my last two moves have each been around 1200-1500 miles, and the one next month will be 1200 as mentioned. I usually only do this once or twice a year, as my jobs are usually 6 months to a year or so.
I have an F250, it's a great truck, very powerful, fully loaded, about as nice as you can buy. However, I do think it is overloaded beyond the legal limit still with the trailer, not due to the weight of the trailer itself, but due to the hitch weight in the bed of the truck and all the weight it puts on the rear tires. I have air bags, but that doesn't compensate for the weight it puts there. This is another reason I am possibly considering a F350, Dually, gas truck. The dually has over twice the hitch weight capacity, which would make towing in that aspect much better, the power just wouldn't be there (but doabale with the right gear ratio)
I don't haul stuff at work, and typically about 95% of my driving, other than the towing, could be done with the Camry. On weekends when my gf and I do separate errands, we do drive separate ways, and even then, that's not too often, especially now that we have a washer/dryer in the 5th wheel (she used to get groceries while I'd go do the laundromat).
As for the oil changes and fuel filters, I could probably do the fuel filter myself as the labor is so absurdly high and it's not much work (I've been to Ford's all over the country getting fuel filter changes, they all end up being $200+). In regards to the oil, to be honest, I work a lot, don't have a garage or concrete driveway, as much as it sucks I don't mind paying someone else. When I work 60 hrs a week and spend 3 days after work at the gym, last thing I want to do is get home from work at 6 and then change the oil in my truck on my limited free time. Fortunately, my hours are usually 50, but occasionally work Saturdays (have been a lot the last few weeks).
For the tire, I am running Toyo MT's, obviously bought pre-mustache days lol. They have been great, they just don't last as long. If I do keep my truck, it won't be my DD anymore, I may be ok buying them again as they would last 4+ years instead of 2.
The problem with older vehicles, even a 7.3 which I would love, is none of them have the towing capacity. A 2001 F350 Dually, has a towing capacity of like 3000-4000 lbs less than my F250! The new dually's have about twice the towing capacity of the old 7.3's..
I'm going to heed your advice about driving the Camry to work (I have all this week and last week already) at least until I can decide more set in stone.
If I decide to keep my truck, I will talk to my company and switch my "work vehicle" from the Truck to the Camry, that way they will pay for the gas in the Camry (They'll only provide it in my "work" vehicle) and then only use the truck to move and occasionally when my gf and I need separate cars. They will still pay for my trucks gas when I move, even if it's not my company vehicle as it's a moving expense.
The other option, is either getting a Gas 2009-2012 F350 Dually. It will be more stable pulling the trailer, but less power. Maintenance will be less, but I still wouldn't drive it much anyways. It wouldn't be under warranty likely, but if I'm only driving around 5,000 miles a year, I should be in pretty good shape. One of these with around 50k miles costs between 22k-30k. If I found one for 22k, and broke even on my truck in a couple months after I move, I would be saving about 14k-15k. After my 401k and Roth IRA, that's about 5-6 months of savings.
I think even if I keep my truck but quit driving it so much, I will still come out pretty ahead. I will just have to be diligent in driving the camry, especially if I have to start paying for my own fuel in the F250.
