Older engines ?
I have been looking to find a suitable truck to replace my 2006 that is going away, I have narrowed it down to the range of 65-69 either in a f100 or f250, depending on what I find that fits my fancy. First question, how are the 65-66 f100's at pulling small trailers? Am I just being wishfull that a 66 f100 would fill my needs and still look good in the process? I have a larger vehicle (Escalade) to tow the travel trailer and real heavy loads, but would like to have the f100 or f250 to be able to haul items as well.
Second question, any issues with using current fuels in these original engines?
I appreciate all the collective knowledge that this site has to offer.

One thing to keep in mind (you prolly know, others might not) gasoline used to have an octane booster - tetra ethyl lead that is no longer installed in gasoline today. The valves/valve seats on original motors will wear rapidly with modern fuels if you do any kind of highway driving or hauling under load. So you have to factor in getting hardened valve seats installed in the heads. The older engines can have the timing retarded a bit to take advantage of substandard fuel no problem.

welcome to FTE and these trucks do just fine with a load you can make f100's get better gas mileage of course than the f250 due to the lower gear ratios, but you can work the f250's harder with less issues, and f250s have better brakes than the f100s do ....... on motors the inline 6's are good torquey lil motors but not exactly for everyone... advantage is better gas mileage and longevity than most.... disadvantage although torquey and has great bottom end don't just expect to fly down the highway at high rates of speed with low gear ratios.....FE's like the 352 360 and 390 + are workhorses dependable will pull anything you care to hook onto.... disadvantages are they have been known to like gasoline and make an annoying ticking noise (very common by the way) 360's still last forever 
............. small blocks are good in these trucks, big blocks are also great (if not better, the argument never ends) its all in your preference and whatever you find enjoy whatever you get and again welcome to FTE

All 1965 F250's have 12 1/8" x 2" front/rear drum brakes as do some 1966/72 F250 2WD's.
12" x 2 1/2" front/rear drum brakes introduced in 1966 F250 2WD's, were standard equipment on Camper Specials and with a 7,500 lb. GVW
1968/72 F250 2WD & F350's were available with optional front dual piston caliper disc brakes. The rear drum brakes with discs are 12" x 2 1/2."
1965/72 F100/350: 240 1V I-6 standard equipment, 300 1V I-6 optional.
352 2V optional 1965/67, 360 & 390 2V's optional 1968/72. 302 optional in 1969/72 F100 only.
1967/72's have more leg room and the cab is roomier than 1965/66's.
What's the towing capacity of the Cattle-Hack? Whatever it is, it's has to be better (despite some opinions) than any of these trucks, plus it has 4 wheel disc brakes.

Agreed that brakes are the downfall of the older trucks. But I wouldn't be scared to hook 5,000lbs or more behind my 71 f100. With a big block F250 I'd go even more. A lot of how much a vehicle can tow or haul is dependent on the driver.

I'm going to semi-disagree and say that a 300-6, added to the F-series in 1965, will do him well too. They put that engine in dump trucks. I think it can handle some towing.

10 ply tires make the world of difference with stability when hauling heavy loads. Down shifting helps lots with slowing down, and give yourself plenty of room.
That truck is sitting on 32x10.5 with no lift, 12yr old grandson is 4'6.
Overloaded? sure, but the truck didn't seem to mind

2X John. The factory front discs on my 68 F250 Camper Special look like they could stop a freight train. With my transplanted 460 and the 3.73 gears I got.....I'll go head to head with that Caddy. Let's hook bumper to bumper and have at it! Ye-Haw!
