Solid rod is not appreciably stronger then tubing because you are not increasing area moment of inertia. So if you were planning on using 2" OD tube a solid tube of the same strength would not be much smaller in diameter. I will do the back of the envelop calculations when I get home later. The other thing to consider is that aluminum does not have a fatigue endurance limit like steel which basically means that if the rod is subjected to cyclic stresses it will eventually fail. That being said if this is a trail rig and you are using 2" OD solid 7075 aluminum rods, you'll probably be alright.
