No welding needed, I just installed a Curt front hitch on my truck and it bolted right in, no drilling, no welding. Needed to trim the plastic air dam a little.
Here's the eTrailer link to the hitch that fits your truck.Two issues with having it up too high are visibility and airflow. If you plan to carry bikes, they will seriously block your vision if they are up too high. In my case, I am using my front hitch for a cooler rack, and a 100-qt cooler will block airflow to the radiator if up too high.
Also beware of bolt-on receivers that mount where your tow hooks are, you don't want to lose use of those when you have a 4x4.
The etrailer link above also has tons of pics of what it looks like installed.
