I'd go 53ft if the price isn't signifigantly more. Per chance you are in a slow spot and can find dry van freight freight, but no temperature-controlled loads, the 5 ft could make the difference between the load or sitting.
In essence, though, a 48' should be fine, as I see more 48' reefers than vans in OTR.
