i dont have that much knowledge on towing, so i wanted to know, if a trailer is towed that has
to much weight for the motor to pull, how much damage will all this weight being pulled do to the motor? will it burn a valve or something?
i already know what happens to a tranny with lots of stress on it. i prefer a stick in the truck i tow with.
sometimes it's not the stress on the engine that's your main problem when towing loads that are over your safe limit. You also need to look at, if you got into trouble, would your truck be able to stop that overloaded trailer. Would your brakes hold out and not burn up going down some steep hill??? Even people that pull trailers that are not overloaded can put stress on their engine if they do careless things. Example: climbing hills with OD on. When you hear the transmission excessively "hunting" for a gear or switching between OD and the next lowest gear, that's when you need to switch it off. This can happen even without towing anything, if the hill is steep and long enough. I also believe in proper maintence and oil changes. Listen to your engine.
I agree, if properly maintained, your motor should be the strongest link in your drivetrain. If you are overloading everything else, its time to trade for a bigger truck!!
I finally towed with my new used '95 F150 supercab 300 I6. My trailer is 2000 lb loaded. I have a 5 speed OD manual. I never used OD while towing. Was cruising along at about 70 mph in 4th turning around 2500 RPM. Only possible notice of stress I saw was that it used about 1/3 quart of oil in 700 miles. Considering the load, the intense towing speed, and that for about 100 miles of it I was bucking a severe headwind that made me have to keep it nearly floored it to go 68, I guess that's not bad. (Under normal wind conditions I can go over 70.)
