I loved my IFS trucks, with a proper build and good gussets on the steering you can just about go anywhere and still keep the streetabilities. I never had much issue with the half shafts and the weak link is the inner axle shaft on the short side, it is very short and has no torque flex at all. Even saying that I only broke one and was being a throttle jockey at the time and only had to replace two half shafts and they were just wore out. You will want to gusset the steering idler arm or carry a spare (they are a Toyota recall item) as is the steering rod. As a guess they've already been replaced by the recall. Never had a single hub issue as to their strength and I always carry a spare of my 85 haven't broken one on it either. 33's or 35's max on tires I've run both, if you have an auto it will be much easier on front end parts over a stick since some of the hp is soaked up in the trans.
And to show that you can here's a few pics of mine....
