Irrelevant- unless the bed load restrictions are specified in the door jam labels that meet DOT regulation, it’s irrelevant.You can not dismiss the 661lb. warning in the 2022 & 2023 manual. For safety and warranty reasons. As Hyundai Consumer Affairs did me, when I asked about it.
Manufacturers are required to place a yellow sticker on the door jam, if any thing, such as accessories added, impacts the load capacity.
They can’t deny you warranty coverage, if you have complied with what ever is outlined on the door jam plates.
