Why should Tukhemin roll when not in dolly mode? The answer is simple. You can get four guitars and their cases from here to there relatively quickly. If a Tukhemin is fully loaded, you may need 36″ doors (depends on the depth of the cases). Nevertheless, getting from stage to backstage is relatively quick and easy. Similarly, getting from backstage to the truck or van is a snap. In a more domestic situation, moving instruments from the family room to the utility room to make space for guests is a very easy process with Tukhemin.
I suppose that it is necessary to state that Tukhemin are not personal transport devices. Please do not ride them or sit on them in either the dolly or their fully erected conditions.
