I have a 1995 Ford F-150 with the inline 6, 4.9 liter engine with 5 speed manual shift, I have a trailer that is almost 5,000 lbs, with a tongue weight of 300, will it be a problem for the engine to pull the trailer
My friend towed a 2 ton boat with a rice burner truck for two years.. Then a valve burned.
You might wear your clucth out faster. Keep your RPM in the mid-range ( Less stress on the motor ).
If it is a 5-speed I would not put it in 5. Unless you are going over 65 mph which you should not anyway..
Let us know how she tows. I have the same truck, but my trailer is only 2000 lbs (and I haven't even towed it yet because I just got the truck in Nov). I definitely think you should not use 5th gear (assuming, like mine, it is an overdrive). Does your truck have the towing package? What rear end ratio do you have? Also, as a rule of thumb, tongue weight should be about 10 to 12 percent of total trailer weight. With only 300 lb tongue weight, I would expect your trailer is probably misbehaving in some way, such as fishtailing.
I have pulled it and it pulls ok, thank god for the granny gear, the rear end is 3:55 and I put on air shocks, the tongue weight is 500lbs not 300lbs, it also has surge brakes, putting on a front trailer hitch, that way it is easier for me to back it in the side yard. do not have much room before hitting the wall..
Great tip--a front hitch. I have the same problem trying to put my 16-ft trailer into the back yard with a single width driveway and a sunroom that juts out into the yard next to the driveway. I have been pushing it back onto the grass and it is a real bear. You have a good rear gear. Perhaps you could tow in 5th gear--I don't know. My rear end is a 3.08. I have the tranny ratios for the Mazda 5spd manual that I got from a Ford dealer. I have 2wd with supercab, 4.9 six, F150. I don't know if the ratios are the same in your tranny but may be (the heavy truck uses different 5spd manual). FYI here they are: 3.90, 2.25, 1.50, 1.00, and 0.80. If you have a tach you can verify these ratios against your overall ratio (tranny * rear) and calc the tire diameter corrected for squashing on the pavement (maybe about 4% diameter reduction from the tire size).
