- How should I size refrigeration capacity?
- Against the hottest conditions on your actual route, not a regional average. Inland summer temperatures here are severe enough that a unit specified for mild conditions runs continuously and still loses ground.
- Do door openings really matter that much?
- Yes, and they are routinely underestimated. Every opening admits hot air that must be pulled back down, so a unit comfortable on a closed run can struggle badly across twenty stops in an afternoon.
- Can I carry frozen and chilled product together?
- Only with a genuine multi-temperature body giving each compartment independent control. A curtain and careful loading is not a substitute, and it is the most common reason mixed loads arrive out of specification.
- Van or box truck?
- A van where access decides the round — restaurants and small retail in older districts with alley loading. A box truck for fewer, larger drops where volume matters and the delivery points can actually accommodate it.
- Is an insulated van without refrigeration ever enough?
- Only for short runs with product that tolerates some excursion. In inland summer the margin disappears fast, so it suits tightly controlled local delivery rather than general food distribution.
- Do I need a lift gate?
- Once pallets or heavy cases are involved, effectively yes. It should be specified alongside the refrigeration rather than added later, because both compete for payload and for the same rear access.
- What powers the unit when the engine is off?
- Establish this before ordering. Time spent waiting at delivery points with the unit unable to run is precisely where a temperature record breaks, and the arrangements differ substantially between systems.
- How does refrigeration affect payload?
- Substantially, and it is easy to miss. The insulation, the unit and its fuel or battery provision all weigh something before a single case is loaded, so a refrigerated body carries meaningfully less product than the same chassis would unrefrigerated.
