Honestly, it probably could use a good tune-up. Although I would like a new truck, I really don't need to spend the money if I don't have to right now. We'll see how this trip goes and I will get back to you all. Thanks again!

I installed a K&N last year and it seemed to give it a bit more juice.
Our Avalanche has the 5.3 as well but has the 3:73 gears.
The trailer weighs about 6300# loaded.
When heading over Mt. Hood, Oregon (very steep/long grade) we're able to maintain 65mph.


I would love to get a new truck as we're pushing 150K but its not in the budget right now.
A CAI might be an inexpensive way to experiment before buying a new tv.


We also have a "range" in the obd port which keeps it in V-8 mode even when not towing.

The 07's were vulnerable to valve damage due to the v4/v8 gimmick.



I also agree with making sure the Yukon is current with new plugs/wires.


Let us know how it goes.

GM trucks never came with a 3:83 gear ratio... I think you meant to say 3:73 ?

Yeah. My mistake. I must have fat-fingered the numbers when I replied earlier. Sorry for the confusion.

Donít waste your money. Itís obvious that the Yukon is not up to the task. Yes you need a larger TV.

I would love to see your rig maintain 65mph over Mt Hood. I could do it in my Super Duty but it would be unsafe. There are a couple of curves where you would lose momentum and probably have to get down to 2nd gear at 6000 Tom to get up speed again. I drive over 26 once a month.
K@N filters have a use in engines that are used in competition. These are normally torn down to maintain them at peak power. Use on passenger vehicles is problematic because there is more dirt injested into the engine. Call Blackstone and discuss it with them. They have the facts on the increase in contaminants in the oil. Thatís where it ends up. The engine wears faster. I donít believe that any of the truck makers recommend these filters. On my 96 F150 I put on a K@N until my MAF sensor failed because of all the dirt on it. I cleaned it and reinstalled a proper air filter and the problem didnít occur again. I only had 279k on the truck when I sold it.

However, when I got hooked up to the Coyote, the old Yukon really seemed to struggle on the hills and inclines on the highway. The TV has north of 230,000 miles on it, so maybe that 5.3 is getting tired. I've never pulled a camper this heavy before, but it almost feels like I have the old cattle trailer behind me. When I got home the wheels were cool, so I dont think the brakes were dragging. What are your thoughts? Are other, newer trucks bogging down with this kind of trailer, or do I need to be thinking a new TV is in order for reasons other than mileage? Thanks for any help you can provide!
Bet it will pull your trailer.
