Towing and suspension

Hello fellas and lady's I'm new to the group and just purchased my first 2011 Tacoma 4x4 I have a few questions now. First I need to tow this Tacoma behind my RV I know they Can Not be flat towed but if I pull the drive line will it be ok at that point? Or can I use a tow dolly front tires off the ground rear ones will be rotating? Second is Lift and Suspension I want the smoothest ride possable in the desert yes I will be in some knarlly stuff im going to use this truck primarily for hunting and some city driving. I heard a lot of people talk about a 3inch lift im not sure that's enough clearance but 6inches may be to much. Money is not a factor but I don't want to break the bank in the process so 5-6k is not an issue I just want the Smoothest ride possable. Thanks guys in advance can't wait to tear into this baby and have some fun.

 

Any help?
