Front and rear sway bars

I am working on a new to me 2001 28 ft E450 winny sundancer motorhome.
I want to replace the front sway bar and steering stabilizer.
I have done some reading and I think I'll go with Hellwig bars.
There seems to be many different model numbers for a E450 class C.
Can anyone give me any insight on which one to choose?
Or should I just get the thickest one they make?
I haven't driven it yet much, but, I can see the front sway bar is not in good shape so I think I want to replace it and the stabilizer before I have it aligned and new tire put on.
Any suggestions?

PS: and whats this I read about having the caster set at 5 deg? anyone here do that too?

I had my caster set to 4.6 degrees and it helped.

When I had my 2000 E450, I replaced the rear anti sway bar with a Hellwig and changed all bushing, front and rear with polly type.

BIG difference, so much that I didn't do the front anti sway bar.

I replaced the stabilizer and front shocks with a Monroe.

Not sure what you are asking. Using and drilling down the vehicle search you would choose the E450 Commercial/Motorhome selection. There is only one listed for the front and rear. The front one covers 1997-2007 and the rear covers 1997-2021. Both of those are Hellwig's.

I installed the front on my 2007 E-450 and it made a vast improvement. After a couple of trips I installed the rear. I could actually go through a corner without that rolling over feeling.

For sure try to get the caster set to 5-6°. My alignment guy got mine right to 5° IIRC. Even Forest River was telling customers to do that. It can be hard to find someone that will do MH unless you can find an old timer that knows their stuff and has door height. You might need to find a shop that does heavy truck frontends.

I have used several times and their customer service was good. It used to be if you called their help line and asked a product question (make one up) they would answer you then say if you order from me now I can give you $$ amount off. Worked for me!

The Ford Spec for front end CASTER is:

LH +1.3 to +6.8 Degrees
RH +1.8 to +7.3 Degrees

Our unit was:
LH +3.3 Degrees
RH +3.5 Degrees

We added + 2.0 degrees, so we are now at:
LH +5.3 Degrees
RH +5.5 Degrees.

Big improvement by reducing wander at highway speeds.
