Bath and half Fleetwood 2012 Providence. Front toilet keeps stopping up! It always seems to have pressure because when you push dump lever it blows back up every time. It blows so hard sometimes it blows stuff out of toilet. Where could this pressure be coming from? It does this even before there is really anything in the tank. Anybody else had this problem?

How long has it been going on? Was it in storage for awhile? Have you tried flushing the front and the rear at the same time? When was the last time you dumped your tanks? I would suspect a clogged vent pipe but that's based of residential plumbing. I don't know what kind of set up you have in your rig.
Good Luck
I have only had this coach a few months. It has done this since I bought it. It has this pressure even after the tank has been dumped and flushed. It seems to stop up when you flush it. I have looked down in it when you flush and can't see anything. The tube below the toilet has a elbow in it and can't see into the tank. I have been able so far to take a wire rod and hold the valve open and fish it until it moves the obstruction and emptys. Does not stop up on every flush. Seems that the more paper the worse it is.
Check to see if its vent pipe is clear. It sounds like it may be plugged which would allow a positive pressure to build when the tank warms. If the vent is plugged, the only pressure escape is through opening (flushing) the toilet itself.
Sounds as if the vent is plugged. Try blowing a little air (with someone holding the flush pedal down & an old towel over the bowl) from the roof to see if it clears up. You may also try snaking it from the roof.
Sounds too me that when they cut the hole at the factory they let the cut out piece drop into the tank. That's what happened to ours. Until I dug that piece out I had all kinds of grief.
