Brake question
I have a question about brake replacement. I need to replace my rear rotors and pads. What effect would putting the drilled and slotted rotors with ceramic pads on the rear have with stock type rotors and pads on the front? Reason I ask is the fronts are fine and I don't really want to replace them yet. I pull a 9000+ lb TT and am not sure if it would cause a problem having different types of pads and rotors. I am probably a year or so away from replacing the fronts. Thanks in advance for your answers.

First.... I know nothing technical about what you asked. 
But if it was me, and based on common sense, I would do cheapie rears right now,
and upgrade the front and rear when you're ready to cut loose with the big rolls of pocket change.

This doesn't directly answer your question, but for all $265 you can do all four corners at once. I can't imagine that costs a whole lot more than just doing the rears.

I did a lot of research on this outfit, and they have nothing but good reviews (they are also a site sponsor.) I also have a set of their rotors on my Excursion, and I've been very pleased.

If you were doing aggressive driving - such as track or autocross - then you may experience unbalanced brakes. On a street vehicle - especially a truck, then you will not notice a difference. On track or on a vehicle without rear ABS then you could experience rear wheel lockup or enough of a frictional difference to throw off the balance of the car. On an ABS equipped truck you wont have any problems with overall driving dynamics.

There is a minor risk of unbalancing the braking system.
In the good old days of adjustable proportioning valves, you can tweak that to fix the issue.
I am not sure how your can / would do it in electronics with ABS, etc. but it theoretically (doesn't mean practically) can be done.
Slightly too strong brakes in rear is a low risk --- they do very little of the total braking load unless you are trailering.
If you are, the trailer holds them down and prevents them from skidding if you loaded the tongue weight, etc. right.
Bigger question: why do you want drilled rotors?
That is to lighten it, lowering unsprung weight, and in the process, cut your thermal capacity. (braking capacity).
Slots are good, they let gases escape --- and in doing so, actually improve capacity.
The key to a good braking system is to carefully match the material in the rotors with the pads ---- as a combo ---- and ensure the rest of the system is in top shape.
That means new / quality reman calipers, fresh / clean brake fluid, etc.

IMO the rear rotors are just fine. I have not heard anyone having issues with the rears. I would just replace the pad with whatever floats your boat. When its time to do the fronts then spend the $$ and get the cryo power slots and good pads.

If the rotors are serviceable, just have them cut (turned) and replace the pads.
The rears provide something like 20% of your braking power, so OEM equivalent replacement rotors are the only thing that goes on the rear of my rigs, unless I find an upgraded rotor (like cryo'd Powerslots...Cryoslots? LOLOLOL) for an insane deal.
I do like to go with a premium pad though.

To answer your question about unbalance braking I have had no problems with my setup. I just made a 500 mile round trip today pulling 12,000 lbs and the braking was great. I encountered the normal number of idiots that like to pull out in front 10.5 tons of X and trailer at 60 to 70 MPH but I had no problem whoaing up the X.
Also, I replaced the 4 drum electric brakes on my trailer with 4 Kodiak discs. If you pull your 9000+ TT a lot, upgrading the TT brakes to disc adds significant braking capacity to the whole rig.
Hope this helps!
