A few things to consider when making this kind of decision, if you are going to just be doing moderate to hard trails then a dual purpose/daily driver could be considered and this is the way I fly. I dd my rig but you won't find it anywhere on a Hammers trail since I will have to drive it to work on Monday. If you plan on extreme trails don't expect to drive it to work the next day or you will find yourself walking. So if you plan on some moderate wheeling and driving it to work build what you have, but if you plan on trying to destroy your wheeler every other weekend then build a dedicated rig and tow it to the trails with your newly purchased Tundra.
Personally I require my rig to be streetable so that I can drive it to the trail on a day run, just makes things easier when I don't have to load it on a trailer. I can always call my work and have them come and get it/me or have my son/wife bring something to drag my sorry ass home.
