This is precisely what we did. I think of our rig as an articulated, separable motor home.
I purchased the van first. No work was required, other then mechanical maintenance, (it is a 1997). It is not configured as a motor home, more a travel van. By itself, we refer to it as the Limo. It has seats for seven, and the back bench converts to a bed. The TV in the raised roof keeps the kids occupied when we are traveling. I consider it the living room of our RV. The trailer makes up kitchen, and bed room. Four of the kids sleep in the trailer, my wife and I, and the youngest child, sleep in the van.
This is how the seven of us can use a 15' trailer. The only down side in comparison to an actual motor home is that we can't access the kitchen, or bedroom while we are moving.
The perfect trailer for this configuration would be a front dinette 4500 with the pull down bunk over the dinette. That way all the kids could sleep in the trailer, and we could seat most of the family for meals in the trailer.
