For the mattress...we ordered a standard king (bed in a box) memory mattress with the oh-so-important cool gel on top and used super sharp knife to trim one end. Perfect fit. Measure 3x, then start...wait, measure a 4th time. Then slice.
For GVWR, our yellow tag on the truck reads "Occupants and cargo should not exceed 1533lbs". However, the GVWR is 7,200 and our truck on the certified scale with full tank of gas and a few tools weighed in at 5,120, a difference of 2080, not 1533. Emailed manufacturer with the numbers and they replied that 2080 is correct. Kept that mail, for sure.
