['89 Sunrader: aux battery location? Battery isolator location?]

Your battery should be at the rear of your rader behing your storage pod. Flip the pod down and you'll see an access door, That's where your battery will be.

I lost no mpg when I switched to 4.88 gears, but I have a V6 auto. I don't know if the 22r is the same. I would recommend the 4.88's. It does make a big improvement in driveability.

[Timing Belt 3.0 V6 Replacement Frequency]

Lee,

I just today got a quote from my local trusted mechanic/shop for a timing belt, pulleys, and water pump replacement and it came to about $680 total. This was for my 1990 sunrader V6. Hope this helps.

[What's your rig and where's it at?]

Darrell and Niki here,

This is "Agnes" she is a 1990 Sunrader that my folks gave me. They had it for over 10 years and it has traveled the us. This is the 2nd Sunrader I have owned. It is the rear bath model. One cool thing that's been done to it is a gear change to 4.88's. This and a free flowing exhaust really make this drive really nice. She is located on the Key Peninsula in Washington state.

I'll have to get a hold of my folks to see if they have pics. I doubt they would have any digital pics though. Next time "Agnes" is up in the air I'll get you some pics.

Thanks

I just recieved a 21' 1990 Sunrader V6 Auto from my dad. He put 4.88's under it. It did not affect the fuel mileage. I just drove it home 450miles through the mountains of Or and WA and got 15mpg out of it. My dad towed 4ea 4wheelers behind this m/h quite frequently with no issues. So my vote would be for 4.88's. Hope this helps.
