I have an '07 DC 8' bed SR5 4x4 5.7l & Max Tow. I tow a tractor with it. Anything over 4k I use a WD hitch, so I have never noticed the 'frame bend'. I made this purchase based on price, capability, room in the back seat.
I really wanted a diesel, however I could not justify the cost.
The biggest problem with mileage is my right foot. It is hard to keep it off the floor.
This truck is not perfect, but it can do what is claimed.
The axles are heavy, the paint is not. The rest of the drive line is heavy enough to handle the strain of towing.
Being one of the first 5000 built, I have had a couple of issues.
Electric smog pumps failed at 40k, warranty fixed.
Front diff malfunctioned around the same time, warranty fixed.
Lost my floor mats & good throttle due to the stuck accelerator pedal hysteria, thanks to the government & all of you that think that you need three sets of floor mats piled high in your vehicle.
Sorry, that one still ticks me off.
One set of rear axle bearings at 80k. Toyota's vendor resigned these, I found the new ones. Mikeeemo paid that bill.
Brakes.
Oil changes.
Trans fluid changes. For all of you that are going to argue that point, look up the cost of the trans vs fluid every 30k for the life of the truck.
I have never seen a piece of equipment with lubrication failure that was over serviced. Oil and grease are still cheaper than parts.
All in all a good truck.
I would like to see a one ton version. I don't care if it is gas or diesel.
Oh yeah, I tow at 60-65mph and can get 11-13 mpg. The transmission is in tow/haul mode with the shifter in drive.
The salesman told me to haul in manual mode which automatically deselects the 5/6 overdrive and deactivates the transmission programming, that got me 8 mpg on the first trip. I reread the manual and changed the setup to just engage the tow/haul, that solved the poor mileage.
