I’ve had the shocks replaced on our MH was getting a rough ride so I thought I would start there well the ride is still rough up front but now the whole rig is very bouncy over certain highways (like a bouncy house ??) I don’t know what kind of shocks the service station installed but it was a truck shop and to me the shocks seem heavy duty any thoughts about the bouncing up and down.
Thanks,
Ev

Gotta have stiffer shocks (maybe even adjustable coil-overs).

Have you weighed your rig?
What air pressure are you running?
What chassis is your rig on?
Tire pressure can make a big difference.
Proper loading tp balance the rig. After weighing rig, check to see how it compares to your rig's capacities.

As enblethen mentioned....tire pressure really makes a difference.

Have you weighed your RV and set the tire pressure to the tire manufacturer's recommended pressure?

Was the service station experienced with heavy RVs? If recent ask them to fix it.

I haven’t weighed my RV recently but I run my front tires at 90psi recommended is 85psi I have a TPMS and generally the pressure gets up 96psi or so while on the road and my tires are new

What chassis?

What shocks did you just have installed?

If the "85psi recommended" is from the your GVWR plaque? If so, that PSI is based on that axle being loaded to its GAWR. As mentioned by others, this MAY have you way over-inflated. No way to know until you weigh it.

Do not be concerned about the PSI increase while driving. The tire engineers took that into consideration. Their pressure recommendations are "at current ambient temperature before driving".

Need also tire size and ply rating.
Do you have a tag axle?
Even 85 in front maybe too much.
If you have heavy weight behind the driving wheels, it can make the front light and cause bouncing.

Bouncy to me would make me think tire balance .You said tires were new possibly you lost a wheel weight. I wouldn't be over inflating max recommendation on side of tire. That shouldn't cause bounce but will ware center of tires.
