I just ordered the 910lbs for my 2018 Mondo as well. Have not installed yet but commenting as I may need the info you provided when I do go to install. Have you been happy with the upgrade? Current bags that came with mine are Fatsac that measure 46x20x20. So, if my math is correct current bag are 661 lbs each.

Also a driver of my comment is hoping that some on here may be able to shed some light. I ordered upgraded rear locker bags that measure 45”L x 20”W x 25”H – 910lbs.

When converting these dimensions to volume I get 22500 cubic inches. Then converting cubic inches to gallons, I get 97.4 gallons. A gallon of water weighs 8.3 pounds. So, multiplying 97.4 (gallons) by 8.3 (lbs) I come up with a weight of 808.42lbs.

To my question, either my math/info is off, or do these new bags really do not weigh/hold 910lbs, or am I missing something? Maybe I’m not accounting for the extra weight (101.59 lbs) or gallons (12.23) gallons coming from the bags stretching when filled? That just seems like a lot of stretching.
