    2008 F150 4.2L 5 speed reg cab XL longbed 2wd with 8,000 miles at an area dealership listed at $15,950. Ok everyone, here's the same boring epic question: what's your opinion of this truck?
    I have a small car that I love (esp at 26 average mpg) but I really need a light-duty daily-driver truck to knock around in so I don't have to take my 2003 GMC 2500HD 6.0 4x4 to every little sprinkler, pinestraw, or estimate job. Also, I am being serious about getting lawn maintenance accounts this summer, and might think of using this truck to haul a trailer and equipment. I know it's not a gargantuan tow beast, but it would fit the "daily driver" bill better than the 2003 GMC (also the GMC doesn't have A/C). I am easy on vehicles and equipment, and, most importantly, HATE AUTO TRANSMISSIONS. Does anyone use the 6 cyl/5 speed daily that could give me some imput?

    Thanks. Roll Tide.

    Ford's 4.2 V6 is a bored out version of their 3.8 V6 that they used to put in cars and Windstars. Most of them seemed to average about 100,000 on the engine before they throw a rod. They have decent power for a V6, but the life will not be as good as a V8. Ford's 4.6 V8 ran good and would get about 24 mpg empty on the highway. The V8 would be a better choice for the long run!

    I have three 4.2 autos. Two have over 200k and one is less than 100k. That is total bull that they only last 100k. Your statement that a 4.2 is just a bored out 3.8 says it all. You can't bore a engine that far it would be a two cylinders at that point. If it were such a bad engine Ford wouldn't have used it as long as they did. The only down fall to the truck is that the brakes just aren't enough to stop a load, but this could be said about almost all half ton trucks. I picked up two loads of 2400lbs of concrete in my f-150 this weekend with zero issues.

    Thank you both for your replies. I am glad to hear that people have accrued high mileage on these trucks without major incident. Does anyone have experience with the transmission? I believe it's the M5OD-2, which I know is not a HD tranny, but I worked for a guy who ran two reg cab f150s that toted approx 3,000 daily without much problem. The 4.2 doesn't have much aftermarket support (read:none) but has anyone put a cold air kit or something else simple on it, and do they help?

    I have worked at a Ford dealership for 6 years. Just do a google search for Ford 4.2 V6. As for the mileage, I'm sure that you can get more but there were probably 10 V6's to every 1 V8 that needed replaced in those trucks.

    A co-worker of mine had a late 90's STX short box reg cab 4.2L with the 5 speed. It was a quick truck when unloaded and easy to drive. I borrowed it a few times when my vehicle was in the shop. I can't speak for mileage as after a few days it was around 1/4 tank and I just threw $30 in to cover the mileage I put on it. When he sold it, it had 180K on it and still ran like a champ. The norm for any gas engine is around 150K. If you keep up the maintenance and don't exceed oil change intervals you can double that.

    Fuel pump, tank, emission components, exhaust, bearings, suspension bushings will all rot out before the engine will die.

    The 'old' 3.8L had a slew of problems in it's earlier years, but the 4.2L reliability is top notch at the time.

    The 3.8 is an older design pushrod engine. The 4.2 is a Triton truck engine, same basic design (overhead cam) as the 4.6, 5.4 and 6.8 truck engines.

    Don't worry about 5 spd, they all work fine, especially you are picking up some lawn accounts this summer, Ford 4.2 is not that soft like people trying to say. Towing a Z and a wb on a 12 ft trailer like most people do around here, I see everyday, not an issue.
    The problem mostly will happen IF you pull heavy stuff like 3500-5000 lbs or more daily, is the brakes and clutch. These two things are weak on the F-150 manual tranny, mostly the rotors will be shot sooner than anything, then clutch worn out @ 80k or so.
    Also, 4.2 is a very durable engine, I have seen many over 250 k , and a lot of them.
    If I really want to get a manual tranny truck, I would get a least an F 250, so you don't have to worry about weight affecting your brake and clutch, they are built more beefy than the F 150, but if you can't afford or don't want to spend that money, so F 150 is okay. Think about people who still tow with a Tacoma or Ranger, Froniter....F 150 is way better.

    There I go, spouting off when I don't know what I'm talking about. The 4.2 is an Essex engine, similar to the older 3.8.
