Allvan’s default ProMover body spec. standard is 26’ long x 102” wide x 109” tall. Our default cargo body dimension is 26′ x 102″ x 103″ respectively. These standards tend to be what most want, most of the time. Max cubes. Can Allvan tweak any or all of these dimensions? Absolutely. We are custom body builders. We will build what you need. Call to discuss.

So you know, Length is tweakable in 2’ increments. Width and Height can be changed in 6” increments. Sidenote: Allvan attics are all custom spec’d per cab type and height.
