When travel down the road at around 55mph I feel like skip or a jump it's not aggressive kinda light but seems like something is not right.RPM stay the same so not sure what it is and hope someone can help me out. Thanks

It's nothing due to the road I'm about 90% certain it's coming from the drivetrain. It feels like it's lugging or miss fuel at times. Any thoughts on what it might be?

If your read through the link I posted it above, it discusses the issue of frame beaming. There is an updated rear cab bushing that can be replaced to lessen the bouncy ride inside the cab.
