I'll offer some input. It's hard to make an "everything" vehicle. As you add capabilities to your rig, you will be subtracting favorable characteristics from from your vehicle. As you add lift and big tires, your rig's road manners and braking become unfavorable. The truely "everything" vehicle does not exist. Instead you have choose or build a vehicle that is a compromise on all fronts so it does ok on the road and pretty good off road. When you go one direction or the other something must give way. You can have a great trail rig, great mud bogger, great sand dragger, great rock crawler, or great road driver, but a vehicle that is capable of anything you throw at it doesn't exist.
Hope this helps guide you with your choices.
