Hi Bart,
Your not confusing the propane store compartment under the loft with a common storage area are you? There is not much room there unless you go to smaller bottles or remove one. The two small front/side compartments will hold you blocks, chocks, cord sets, hoses, trailer power cord, and small items. Chairs, grills, gen sets, coolers, DO's, and outdoor carpets will need to ride low in the truck bed around the 5er hitch. I hope that answers your question.
