Can anyone tell me the big differences between 2005 h2 and 2006 h2,
I have 2005 h2 but I have a 2006 service manual.

 

The same truck. Wasn't till 08 changes were made.

Thats a great sight and references tool! With the exception of when colors came and went was familiar with 99% of that but I had to learn it thru personal observation and take mental notes.

One item I want aware of was the 2005 14 hp bump, wonder what they did?

 

When I bought mine I was deciding between an '05 and '06. The only differences I noticed were the door mirrors (straight posts vs. slanted) and the '06 has the spare tire on the bumper mount.

 

The '05 also has the rear mount spare tire.

 

For the most part you can no longer use the rear mount spare to determine the year, a lot of them have been swapped around i swapped mine around for the 3rd time ! And if I remember correctly even in 04 there was a dealer installed option for rear mount spare.

 

Was that an option or a mid-year change? I probably would have gone with the '05 instead of my '06 if it had the exterior spare tire mount. It was a tough decision between the two and the spare tire location was what pushed me over.
