We do tow our 2005 Pilot. It is the last year that Honda "officially" endorsed flat towing behind a MH. That said, after we purchased our Pilot last year, I ran across a number a threads stating that other people have towed their Pilots up to model year 2012. I don't recall any more recent model years but 2012 is what has stuck in my head. As imgoin4it said, the drive train has not changed and that's what is important. Maybe 2012 and newer has changed but I don't know for sure.
There is a procedure that has to be followed exactly. Start the engine, shift transmission all the way to 1st gear, then slowly come back up through the gears, then leave it in drive for at least 3 minutes. After that, shift it into neuytra, then leave it in neutral, turn the engine off, but leave the keys in the accessory position. Install your brake actuator, then use your spare key to lock the door and your done. If you stop for more than an hour or so, repeat the procedure to be safe. Just make sure that you DO NOT SHIFT BACK INTO REVERSE, if you do, start the procedure over. The reason being, Honda has the transmission pump attached to the rear of the forward drive gears and it will operate by the movement of the driveshafts.
I think the reason Honda changed there stance and do not endorse it any more, is that too many people didn't follow these procedures and messed up their tranny. Then Honda had to payout for it. Google it to find out for yourself, but newer is doable. I would have bought newer if I had known!
Hope this helps, good luck!
