i have a 1994 Fleetwood Flair class A 22ft, I'm noticing a slight vibration when accelerating when up to speed it seems fine, could it be transmission or u joints, I only has 56000 miles but a lot of years.would appreciate some ideas.........Thanks

My first guess and easiest to diagnose would be U-joints or a carrier bearing on the driveshaft. Usually longer vehicles have a carrier bearing to support the driveshaft.

Sounds like U joints. Also consider loose bolt on transmission or engine supports, I might find someone with a pit and have them check and tighten just to be sure.

Also, a plug wire starting to fail will cause a misfire while under acceleration, causing a vibration.

I have had issues with a truck that was parked for months, then put back in service. Just as soon as stop, hit driveline with greasegun.
And a weak wire or plug often (Coil pack on modern engine?) is first noticed as miss under load.

What chassis is your Flair on Chev or Ford>
I would check the distributor mechanical advance.
Plug wires could be breaking down. Cylinders 7 and 8 on Chev 7.4 can be problematic.

Mine was on a car--a broken engine mount.

That can be a issue that causes vibration, but mounts are unlikely to break while parked. With helper EZ to check. 1 hold brake while apply power, forward then reverse. If mount is broke, can see engine moves.
