I had a 2003 Avalanche which I bought new in 2003. Just sold it this year. It had the original version of the Ramboxes, though quite a bit smaller. Talk to anyone that owned an Avalanche and they will more than likely tell you 1000 ways they used these boxes built into the truck walls. (tow ropes, jumper cables, tire jacks, tire chains, food, fire extinguishers, first aid kits, air compressors, tools etc.) The reason I bought a RAM was the Ramboxes, MFT, Headsup display and 360 camera view. Would have bought another Avalanche if GM was smart enough to still make them. Oh and the AV came standard with hard tonneau covers that were water tight. I'll bet there are many ex-AV owners that have bought RAM trucks with the Ramboxes. The amount of space lost in the truck bed will only effect select uses of the bed, which probably will not apply to 90% of owners. It will not effect hauling of lumber, 4x8 sheets or ATVs.
