while i like the idea of the soft top and wanted one when we first got the taco (best top's site had none and when we e-mailed they told us they were not making one yet), we got a sportz II tent for the bed and were quite happy. a sot top would have worked about the smae for us except given us covered storage when not sleeping in the bed. but things changed, we had twins in april (lucky we had the double cab, it is our only 4 door vehicle) and the sportz II won't fit four even if two are quite small. we need something to cover the bed and soon as shaking off a cold double stroller everytime we want to go somewhere really sucks, and with babies in the back of the truck when we travel all our gear will now need to be in the bed and we will want the gear covered too. the roof top tent is what we are going to move to to sleep all four of us (and we need to get that in time for our summer trip) and i just don't want to go as high profile as a sot top with a rtt mounted yet above that, hence the tonneau with rtt mounted above it. i've e-mailed the expeditions west guy to ask how their rtt is mounted but i don't think they have a tonneau under it...
