Picked up my 2005 5 yrs ago today. Almost 50,000 miles, still only been to dealer once (leaf springs TSB).
-Running Pennzoil Platinum in the motor, Full syn oil for 6-spd tranny, transfer and front diff.
-2 changes of 80w-90 Syn blend w/ no fiction modifier in LSD rear diff. Lays two tracks, no chatter.
-TRD exhaust, sounds good, 5 winters, and only slight rust on welds in/out of the muffler. Well worth it.
-6th winter on Blizzaks tires on 16x7 steelies for Dec- Apr. Prolly last season for this set.
-Stock H/T's were awful in winter, ok for summer. They lasted 30K, replaced w/ a better H/T, Kumho APT KPL51's
-Cut a heavy 5/8" thick horse stall mat for the bed
-Homemade bed extender, makes 5ft to 6.6ft
-Short clutch pedal travel mod
-Added front bed D-rings
-Undercoated the frame Oct 08, helped some. Just sanded and repainted the Tow bar/bumper.
4x4 system: Got about couple thousand mi in 4hi and use 4lo a few times a month. No issues. Despite other posts, minimal loss in MPG using.
Tranny & motor: No problems, 6spd only gets smoother over the years.
Body: Paint is doing fine, wax every 3-4 months. Have a few scratches from brush on the trail and dents around the bed/tailgate.
Interior: Zero electronic issues, seats holding up well.
Composite bed: Other than hundreds of scrathes, holding up great.
MPG: lost .5- 1 mpg this year now that we have 10% Ethanol like everyone else.
Mostly Rural driving,
Avg 19.5-20 summer
drops to 17 in winter
Best 23, long summer trip
Worst 14, Week of below zero and towing
Octane: At least 89. Did use 87 in last summer when was $4.50+, lost only.3-.4 mpg, but at low rpms 1500-2000 (where you get your best mpg), accelerating or hitting any grade is where I really noticed the motor lug and ping more. Heavy loads/ towing even more noticeble.
-The bottoming out with a load and leaf spring squeak, but fixed w/ TSB.
-Frame rust, I'll stay busy undercoating every couple years.
-Weak tailgate, we all know. I use a plywood plank for weight dist when hauling my enduro moto.
-The TRD sport 17 rims are bubbling on the edges. These wheels get to sit in a comfy 40 degree garage all winter.
-Very sensitive ABS, not setup well for winter.
Still want to run it another 10 years. As long as the frame is taken care of should be no problem.
