You didn't say what your camping experience was, tent, pop up or RV. Setting up the TM isn't any more difficult then a pop-up camper and takes about the same time. Our two room tent takes longer, my daughters tent takes less time.
In bear country the TM is considered hard sided but bear camping rules apply just as if you were in a tent. The TM is no more bear proof then any other RV.
The standard TM toilet is unique, it is completely self contained in that you flush with recycled waste water after the initial use.
Because the TM when closed covers the refrig vents is why the fan needs to be run. This is to remove waste heat.
Batteries in any vehicle or RV require attention. RV's require paying a little closer attention their state of charge and fluid levels. Check out the "12 volt side of life" a two page write up batteries.
You didn't mention your type of van but TM tongue weights can be pretty high and may exceed your van's ratings. This can usually be taken care of with a weight distributing hitch, WDH.

The TM is easy to tow, comfortable in inclement weather, and makes the ideal RV for many of us.
