Many of the posts here mention loading clothes, provisions, water, and emptying the holding tanks and unloading at the end. This is the same in any RV. The only real difference between a camper and trailer is a camper has to be loaded, a trailer has to be hitched. If you are in a hurry that's the difference between 20 minutes and 10 minutes. A motorhome is a little quicker, twist the key and go. Except that a motorhome has to be maintained as a motor vehicle (tires, oil changes, smog checks, etc.) so much of the savings in time are lost over a year.
I would not consider the time required to go as a big consideration. Much bigger issues are: is it big enough to keep you comfortable, and will it go where you want to go? A camper sometimes looses the former, but is unbeatable on the latter.
I've had two van conversions, a 5th wheel, a large trailer, a class A motorhome, and 2 truck campers. Every one of them had pros and cons.
