That pic looks like the middle portion of an aftermarket sway bar, and "ipd" is a handling parts brand I'd heard of, years ago. Searching now, it seems they've zeroed in on Volvo, but maybe they had or still have other offerings.
I believe a Lazy Daze will exhibit better handling than most Class C's of the same size, let alone bigger ones. They're lighter and lower than most designs.
Most likely, the Track Bar mounting that clamps onto the driver side frame rail, may compete for physical space with the driver side of an air bag kit.
I also added a BlueOx Tiger Trak Bar. It's not as easy as sway bars, and the attaching clamp is a little hard to visualize. I called BlueOx support, and shortly received a call from their handling specialist, Mr. Ralph Andrews. This was several years ago, I don't know if Ralph is still there. He was very helpful with my questions and clearly had depth beyond somebody reading a troubleshooting flow chart. He said he'd actually designed most of the rear track bars in the market. Also confirmed most of them are the same for a given application, just different branding, numbering, and paint color. Said they were all made by one plant in Pacific NW.
Anyhow, if anybody can help with an install question, I'd vote for Ralph. Failing that, John Henderson at Hendersons Line Up in Grants Pass OR, or Eric Davis at Eric's RV in Sequim WA.
Sway bars made the big difference, but track bar added more improvement.
For Brother Ron Dittmer: Having a sway bar and a track bar didn't seem to create a conflict. Problem I had was getting the track bar to clear something, and I forget if it was the differential cover, or the front of the fuel tank. Ralph assured be it'd fit if I forced the clamp forward, along the frame rail, as far as it would go. That meant hard against a crossmember.
We always have to be careful not to pinch something like fuel lines, wiring harnesses, brake lines/cables, etc. There's more risk of doing that with the track bar clamp than the sway bar link mountings. Track bar has bigger fasteners and requires more torque than the sway bars.
