I had no idea this even existed. What a time to be alive!
I've been running weight safe for a few years.
And my sig shows I tow all kinds of random shtuff. Lol

Actually have two because the first one I bought was steel and was only a 6-in drop which ended up not being enough for me.
I actually have 2... Looks like prices have gone up as well.
Tried to buy a new 8-inch drop for it and I didn't read properly and that one was aluminum so I ended up having to buy a whole second hitch essentially. The steel and aluminum do not fit together.

Looks like they offer a weight distributing option now also.

With that much load, I strongly recommend a weight distributing, sway control hitch. I haul our TT with a Camco Recurve R3. Works great.

Yea I am researching that also. Would give me pease of mind for sure ... just not certain how necessary or not they truly are.

got the last of sound "deadener" installed - just did floor in the back, rear hatch, and over the back of the wheel wells

> Amazon Basics Car Sound Deadener, 18″ x 32″ (9-Piece) <

I don't have anything to compare it to as far as other brands, but this stuff is working pretty well
I used some of that as well. Sounds crazy but I had good effect by sticking some to the plastic wheel well liners on the side opposite of the tires.

Maybe I can provide a little more perspective. I've hauled four different trailers behind our 2012 Yukon XL:

1/ U-haul car hauler with a '96 Acura TL on it. No WDH and only had to cover 100 miles or so, but I was glad when I got done with that trip. The backend was really squatting even with the rear air shocks due to the tongue weight.

2/ 5x10 cargo trailer with a 3500 lb capacity. No WDH. No problem - easy pull.

3/ 18' camper with a total weight of 4200 lbs. No WDH. More squat than I'd like, some sway with passing trucks, but not white knuckles. Anything bigger and I'd have invested in a WDH with sway control.

4/ 32' camper with a total weight of 7500 lbs. Good WDH and sway control. Still squats some but the airbags take it all out and it handles like the trailer is welded to the Yukon.

Back in the day I did the entire floor, firewall and roof skin of my Mustang with Peel-n-Seal roof repair membrane. My car smelled like tar for 2 weeks, but the stuff worked really well and never came loose. It was still solid when I parted the car out years later. It's $1/sq. ft. The Amazon stuff, while much cheaper than name brand products, is $15/sq. ft. It's probably more effective. But I doubt it's 15 times more effective.

It’s all just butyl rubber with a foil face, in varying thicknesses- sound deadener or that repair material you linked. Nothing special. If that stuff is thin you could always double layer it and it’s still only $2 a foot.

Well, looks like the cold finally got me and will need to be on the hunt for a replacement battery. Never thought the existing (in it when bought) one was all that strong but the sub zero temps exposed the weakness. Went to remotely start it and she was like, ummm, F-U pal! Slapped the battery charger on it for the time being - sigh!

I’ve been pretty happy with my Optima red tops.

3 hours on a charger did nothing - ended up jump starting it. After driving around for about 30 minutes or so, brought it home and did turn it off. I restarted but I could tell the battery was not happy about it.

Changed oil today.

When i got the truck in September i put Fram TG10060 filter on it and Penzoil 5w-30.
Had an oil pressure on lower side ( 40 startup cold, fully warm 18 at idle and 22-25 while cruising at 1100rpm on highway ), but according to other posts that seemed in okayish range for these trucks.
I though my pickup tube is bad and was going to replace it in the summer.

This time decided to go with ACDelco PF48 and Mobil 1 5w-30 High Mileage.
As soon as the oil was changed my cold startup pressure shot up to 55 and now cruising pressure at fully warmth is 40.
The idle on warmth is now 25.

Crazy! Did i have a bad fram filter?
