Ability prevails.
We also had no problems that couldn't be learned away by seat-time.
I'll guess 95% of rv owners do not have handling upgrades.
Below is a link to most of my modifications either accomplished or pending.

Personally, DW became very opinionated abt “side to side” sway.
- So we installed the more robust Helwig anti-sway bars vs the OEM sways that do very little to eliminate sway.

Also, as been discussed on many threads…
- a professional alignment with proper caster settings will eliminate virtually all driving difficulties

Here’s one comment on alignment I shared with the local shop:
“The caster should around -5.1 degrees on the driver's side and -5.3 degrees on the passenger. You need a little more on the passenger side to compensate for the crown of the road or it will tend to drift to the right. This is the range that Forest River now suggests for the Ford E350/450 and when I asked the technician that aligned my unit for these numbers he said that was about what he normally used.
*You will need adjustable bushings (I bought Moog 80109 bushings) since the factory bushings are not adjustable.
*Or you can use shims to adjust the caster.
*At the same time I would have them check the ride height in case the springs have sagged.
*The suspension on the front of the E series is independent but still pretty crude so when the suspension is compressed (sags) it develops negative camber and this wears out the inside of the tire(s).
*The toe-in is stock Ford which is ‪1/16‬" to 1/8".
*By the way the caster settings are higher than what Ford sets at the factory but they say you can increase caster up to -8.0 so these numbers are well within Ford's service recommendations.

As above not enough caster and a toe-out setting make the unit very unstable and tend to wander in wind and from passing trucks.
*I do not understand why Ford does not put the proper caster in at the factory since they offer a motorhome package so they know there is a motorhome going on the chassis.
*Although in Ford's defense my 2016 came with 4.2 degrees of caster and did handle quite well but going to 5.3 made it even a little better in crosswinds.”
