You wouldn't have a shower in a van but when there is no cargo you have a very large "sleeper" area equal or even larger than many straight trucks. I had a G3500 extended. I had an Onan 2800 Quiet generator, Coleman roof air, Fantastic Fan, inverter, hotel battery, microwave, pretty much every comfort and convenience I wanted. The drawback was not standing up straight. If I were to go back in it I'd go with a stand up height van. I drove all 3 sizes starting in T/T then S/T and ending in a van. I did ok in a van and liked the freedom it gave me to go/see/do things. I'd only go back out if I went in a van.
