A final wrap-up -
I cannot believe how spacious this 5th wheel chest is!
Everything, but a single ice chest fit in the chest and we are on a trip that has us bringing everything, but the kitchen sink. Nothing extra in the TT and nothing at all in the truck cab.
3 cases of H2O, half a case of ale, generator, gas can, step stool, bike helmets, baseball gloves, and on and on. It's like having a trunk in a truck. Weatherproof and lockable as well.
