@TexasTJ you need to jump on that bumper swap w/
@tdhunter13 and work out a cost difference; that's half of your problem solved.
As far as weight:
Been cruising around with my new dual swing-out prototype with a spare and two full Jerries (1 x fuel/1 x water), propane is currently empty (add 3-5lbs) and my loss is consistently just shy of 2 gal. (I always round up as it is much more of a reality check). Of course I have a FR full rack, TR front and rear bumpers, and TF sliders; just a weighted swing-out alone is killing my mileage another 2mpg. Part of the lifestyle......lol
On that note, this is solely to work out any vibration etc. Then I will remove everything and get a solid "Empty Weight" of Victory. That means, just like in aviation, anything that is not removable before we get a "useful" weight from our "max gross (OEM spec)".
I'll weigh with bumpers, rack, sliders, empty swing-out, near empty fuel tank, full operational oils, and a completely empty interior except was is not normally removable.
Hence, EMPTY WEIGHT. Compare that from what JLR says the LR3 "originally/stock" weighs empty; subtract that from JLR Max Gross weight and that leaves "USEFUL WEIGHT" for my (Victory) LR3 before I hit the OEM specified MAX WEIGHT.
I'll go on the record and say that with all of the OEM interior stuff I took out; seats, paneling, etc. and then added back in with overland specific configuration such as my fridge/freezer (removable I guess), sleeping platform, etc. I am definitely lighter than stock. My bumpers, sliders, empty swing-out, and KM2's; no doubt I am way heavier than stock but the delta is not as great considering I modified with weight cutting in mind to offset some of those trail necessary upgrades.
