This is not the first time Ebay has under estimated the shipping cost on calculated shipping. This is not acceptable. Please fix.

The $80 "other charges" is a FedEx "Oversize Charge" and does apply to that package based on the L+G criterion: L+G = 58"+2(34"+6")=138" > 130" threshold.
It is also subject to a $12 Additional Handling surcharge since the longest side is longer than 48" AND second longest side is longer than 30", but FedEx waives that surcharge when oversize surcharge applies.
Dim weight = 58x34x6 / 166 = 72lb but the Oversize state means it ships at 90lb base rate
Any Delivery area surcharge would appear as other charges, and there isn't anything else that gets rolled into the transportation cost other than Fuel and Residential Delivery surcharges in this case.
FedEx Ground Fuel SC rate = 6.25% (since mid June), and Oversize charges are being included in the Fuel Surcharge computations, so working backwards, we are looking for a base rate around
$80+$56.85 / 1.0625 - $80 - $3.60 = $45.20
Base rate for 90lb to zone 4 is $45.86 which is not the $45.20 amount but is close enough (eBay seems to use "made-up" fuel surcharge numbers)
Approaching this by lashing up a "print another label" on one of mine results in exactly the same numbers as OP's label for a shipment to zone 4, with a base rate of $45.86 and a Fuel Surcharge amount = $7.39
[At the correct 6.25% Fuel SC rate, the Fuel SC should be ($45.86 + $3.60 + $80) * 0.0625 =$8.09 At 6% we get $7.77 and at 5.5% we get $7.12. Always seems to be the case and no pattern is obvious]
Anyway, looks like an oversize 12lb package to a zone 4 destination.
The buyer paid $116 which is a bit less than the actual label cost after discounts of $125.61 I'm vaguely recalling that I reported an issue with FedEx oversize issues earlier this year, with the calculators not properly calculating amounts for oversize shipments when determining amount buyer pays. Have to go find it.....

Here is the text of my post there for those of you that don't/can't access the PS board (I'll be barred myself in a couple of weeks when evaluations come in on the 20th due to no sales to maintain PS status. Guess I won't even be able to look at or refer to my old posts like that one after that.

I don't do UPS, but will show you the FedEx breakdown.
104x11x5 item has an eBay FedEx Dim weight of 104x11x5/166=35lb (which will turn out not to matter along with the actual weight)
Length+Girth = L+G = 104 + (11+11) + (5+5) = 136 in
It hits 2 criteria for $80 oversize surcharge (L > 96 " and L+G > 130"), and as OS rates at 90lb min billable weight.
Base rate for FedEx Ground/Home Delivery for 90lb is $40.20 to your own zone and $73.55 to zone 8 (California).
With the current 5.5% Fuel surcharge, $3.60 Residential Surcharge, and the $80 oversize charge added in that comes to $126.21 to $161.39 which are undiscounted, list rate amounts (what you would pay with a standard FedEx account at FedEx.com Note that these are NOT counter/retail rates which are even higher)
eBay offers sellers pretty good discounts* (up to 40% or more at times) on FedEx shipping. Those above undiscounted amounts become $120.22 to $146.78 if shipped via eBay FedEx shipping (or via an eBay linked FedEx account)
*discounts are only on transportation costs (base rate, Res Sc, etc) and don't include additional charges like the $80 OS surcharge
That is about as good as it gets for something that long. USPS won't touch it at all (L+G>130")
If you can get better negotiated UPS rates that would be the way to go.
The sellers in Texas with free shipping? One advantage they have is the more central location. Fewer destinations are zone 8 from there. Other than that no idea. They must be losing money - there is no magic $30 or $50 or even $70 shipping for an item like that.
Maybe they did quick quotes, used the 30lb weight as the shipping criterion, and didn't enter the dimensions (I'm always amazed at how few people understand the terrible impact that volume, length, and size in general have on shipping these days.)
I suspect both those sellers are going to get rude awakenings.
New eBay FedEx Ground Shipping Calculator Bug That Turned Up Here
The eBay estimating calculator (http://www.ebay.com/shp/Calculator) came up with $101.11 to $124.22 which are completely wrong amounts and too low. Unfortunately, that's the same calculator that produces search result and listing amounts and charges the buyers.
The estimating calculator is ignoring the OS 90lb min billing weight change that occurred on 1/22/18, going by the old pre-1/22/18 criteria where greater of actual or dim weight is used, and is using the dimensional weight of 35 pounds to compute the base rate.
(roughly checked by looking at the differences in base rates for dim weight of 35lb and 90lb billable weight, the difference between the results produced by the calculators, and adjusting with the approx 25% discount that was applied - numbers check to +/- $1)
Which is wrong. That means buyers would be undercharged, in this case by approx 15%. We have another FedEx shipping calculator bug here trinton@ebay
Oversize Charge
An oversize charge applies to packages that exceed 96 inches in length or 130 inches in length and girth. Rating will be based on the greater of the package’s actual rounded weight or dimensional weight, subject to a 90-lb. minimum billable weight.
Effective Jan. 22, 2018. Prior to Jan. 22, 2018, an oversize charge applies to FedEx Express packages that exceed 108 inches in length or 130 inches in length and girth, and FedEx Ground packages that exceed 130 inches in length and girth. Rating will be based on the greater of the package’s actual rounded weight or dimensional weight.

Yep, estimating calculator comes up with $116, which is what would show in search, the listing, and be charged to buyer. It appears that that bug from March 2018 was not fixed. Calculator is ignoring the 90lb min billable weight consideration when a package is oversize.
Specifically, it ignored the 90lb minimum billable weight, and incorrectly used the 72lb dimensional weight instead.
Base rate for 72lb to zone 4 is: $33.88, so total amount should be approx:
($33.88 +$80 +$3.6) * 1.0625 - 0.25 * $33.88 = $116.35 which is pretty darn close to the $116 buyer was charged.
OP is entitled to a $9.61 credit from eBay for their mistake. @trinton@ebay @iprefervintage @dtexley3

Hi @iprefervintage, I will get this passed along to our shipping team to review for potential improvements. Additionally, I looked into this and can see that the cost of the label ended up being significantly less than what was initially quoted as the weights and dimensions that differed from what was in your listing details. I recommend you touch base with FedEx on the measurements they recorded when they received the package so you can make any necessary adjustments to your package dimensions in the future.
