Fosscore's 2013 Suburban LTZ Build Thread

[Fosscore]

Woke up too early this morning so I washed the truck before the sun came up. Couldn't stand the layer of dirt from the constant rains and wanted to tempt fate and the thunderstorms today ...lol

Have a 3.5hr road trip for lacrosse tournament this weekend and you know...a clean truck drives better. Kinda like new shoes made you run faster as a kid.

Even gave the paint a quick wipe with the spray below just to keep the surface slick and shiny. I posted this before as I have always been partial to Collinite's products. I've got some Lucas Oil Slick Mist and some CG Synthetic Spray Detailer that is nice too. But do love the Collinite's. I'll have her washed again on Sunday after our 600 mile road trip. Not a bad way to spend Father's Day with the family.

My buddy was able to source the radiator the same day, so I left the truck at his shop for the night to be completed on Friday morning.

There are some good ACDelco wholesalers in your neck the woods and up in West Palm that we used for decades. Up here, not so much!

Glad she's back on the road. At this point it is age and not mileage catching up with her, we're experiencing some of the same issues with our 2013 Sierra that we bought with 75K miles on it.

When it rains it pours …. For me anyway Foss….. looking good… as always

 

[Fosscore]

223 miles 15.2mpg on the way up with some initial around town miles.

+\- same distance and 17.9mpg on the return trip back down south.

That’s the best I can get with 74 mph cruise control setting.

Pulled into a rest area. Some guy complimented the sound of the truck. Said it sounded good. Wife said yes it does.
Thx @07Burb lol.

2 massive thunderstorms on the way up and during the Saturday morning games. Gusts of wind left a few shade tents broken and a graveyard for trash pick up after the tournament.

The truck still looked good other than some love bugs. I have to say the Collinites did a great job.

Gotta scrub the bugs and motorway grime off. Already vacuumed and cleaned the Husky mats.

The fields were mud soup on Saturday but no lightning so no stoppage of play. And Sunday the mud in some areas was ankle deep. The girls were a mess so we washed them down with bottled water lol. Then drove home 3.5 hrs.

Those socks and cleats were white. The socks are now soaking in Oxi Clean and the cleats got hosed out.

After the trip up.

Thx man. Yep age, but painful all at once. She ran well this weekend.

Oh it poured right out of the wallet and from the heavens. Lol

Thx man. Good to see you , like me still here.

That surprises me for the 5.3L. I can usually get 16-17 from the ESV going, uhh, a bit faster on the highway. At least you can use regular, so I guess that’s the savings. Lol.

IDK. It’s tuned for mid grade. Looking back over long trips it seems to be the norm.

Maybe I need to roll Umm a bit faster. Lol.

The faster movers just blow by and that’s ok too.

Not to hijack, but I’ve found in my 2012 5.3L burb (no tune) on the highway that running at approx. 2k rpm (driving safely, as conditions allow) yields the best mix of mileage & speed. Anything higher or lower seems to decrease the mileage.

No hijack and always good info. Funny, I was right on that 1900-2000 RPMs. Pegged at 74mph as the 75/76mph had an exhaust note that was higher, so I dialed it down to 74mph and kept it there.

Didn't find a need to go to 80mph like the rest of Sunday traffic and only punched it to pass a slow mover in the middle lane (had to run I-95 vs turnpike), which gets much more bearable once north of Jupiter/Ft. Pierce compared to down south = nightmare!! lol)

Found photos of my first truck.

1983 Toyota SR5 4x4 short bed, manual w/ 31" tires.

Dad said I couldn't go muddin' unless I had a roll bar. Limo tint.
Rancho suspension with added leaf springs. Alpine pull out cassette receiver with Rockford Fosgate Punch amp, crossover and 10" behind the seat. No A/C. Awesome truck.

Had some other "cool" 80s add ons. Wink 5 panel chrome louvered mirror. Dual wipers with the blades on top. Dash mat. Color matched fuzzy seat covers. Color matched visor. Custom 80s color appropriate graphics. Even put pink shock dust boots on at one point. Chrome louvered gas cap cover and rear cab strip below the sliding window. Chrome grille. Diamond plate bed rails. Spray in bed liner. HD tube rear bumper.

Did some detailing today.

Washed, tires foam cleaned and light shine, Rain X, coated the paint in Rupes Uno Protect Polish and Sealant, Meguairs leather wipes on the seats, cleaned the engine bay and shined with some 303, Cerakote ceramic wipes on the windshield cowling, interior wipe down and vacuum.

Wife (no fault of hers) must have run over some fresh paint (because never any multiple construction projects always in perpetual motion with no end date) that spun up in the wheel wells and running boards.

Dug around the kitchen and found the Scour Daddy pad and removed the paint from the wheel wells.

The repair I did to the drivers side interior grab handle with some spray foam a while back needed to be removed, but didn't want to ruin the texture or use something too harsh and melt it. Turns out Goo Gone and a light/repeptive scrub with that Scour Daddy took care of the residue and back to spec.

Finished up and having lunch with the wife and daughter and boom!

Thunder cracked and then it rained like crazy for 2 hours after. Never in vain since it just sat in the driveway. Dried the paint again and coated with Collinites 520 Mister Collins detail spray for extra shine and water beading.

Pics because you have never seen this NNBS clean.

Put new double-sided tape on the passenger side LTZ letters.

Put the new registration sticker for 2024 on.

Wiped the paint down....and....heavy thunderstorms rolled through..lol.

Measured the ground to fender lip just to satisfy my curiosity >>
Fronts 34 3/4"
Rears 35"
