Both are rated about 5000 max for towing. Good luck on that.

Yes, for only 30K you can go out and buy a Kia or Hyundai SUV, that is so capable you'd be shocked!!! OR, you can spend 70K+ for a "new" Suburban 3/4 ton if and when they become available to the general public!!! Or as stated, 100K+ for a "new" Excursion from a builder.
As for us, I am fine with spending $2500-3000 on my low mileage Excursion, a lot better than a $800-1200 monthly payment!! To me that ain't stupid!!!

The most accurate gauge in the dash is the speedometer...how else can the LEO's &a courts uphold the speed laws
The dash speedometer gets its input from one of the onboard computers, which can get its input from an ABS wheel (which one?), tranny tail housing, the tranny, our maybe the diff...*ALL* in concert in reference to the look up tables...why reprogramming on most is required
Or, be able to noodle the difference in your mind without reprogramming and adjust accordingly...

Change rear end gear for 2-3,000 dollars on an aging SUV for occasional towing?
Nope. Not wise.
Save that cash for a new SUV instead.

Remember to change the parameters in the PCM when you're done.

Changing the final drive ratio does not require any adjustments to the PCM parameters. The speed is read off of the tone ring on the ring gear, so it is actually reading the tire revs and uses the revs per mile to calculate the speedometer/odometer readings. Changing tire size (diameter/height) would need the revs per mile to be adjusted in the PCM to have the speedo read correctly. I have changed both gears (3.73 to 4.88) and tires (31.6' to 32" to 35.28") and verified speed with GPS, gears didn't affect speedo but tires did.
