We have a 07 Rockwood 8318SS,the furnaces is a Suburban NT-30SP,I can feel warm air coming out the floor vent just not much force. It was 40* yesterday and took an hour to get to 60* maybe I'm expecting to much. Dose it sound like it's working right ?

Thanks Jerry

20 degree rise in an hour is not too bad.
Make sure the return vent or grill is not blocked.
Open any cabinets that may have flex hose from the furnace running thru them
and check that there are no smashed or kinked hose.
If you can access your furnace you can check to see the hoses (probably 2-
one on each side) are firmly connected and one hasn't fallen off.

It doesn't blow like a hand dryer!
An hour for that much temp gain is ok I think.

I have an 08 - similar problem.

Remove the outer furnace cover (located inside) and look through the square hole in the floor at the plenum (can) where the hoses hook. Mine was poorly fastened and dropped down about 2" - most of the hot air was blowing under the trailer. Fixing that made a big difference.

Of course it could also be something else - loose ducting, etc.
