Has anyone upgraded their shocks on Tab 400 Boondock?

Question:  has anyone upgraded the shocks on their Tab400 boondock edition?  I ask because in only our second season we suffered a break where the kitchen sink pipe joins the gray tank. I can only surmise this was the result of bumping down the interstate. I thought buying the Boondock edition would protect us from such damage, but since it didn’t, I’m wondering if anyone had purchased more forgiving shocks. Ours is a 2023 Tab 400 Boondock. Thanks

    There are no shocks.  The Boondock just has a higher ride height torsion axle.

    Boondock is just a minor body lift.
    Original TAB models had 'standard pitch' axles while the Boondock uses an ~2inch height increase higher pitch angle axle.

    All axles are the Torsion Rubber 'spring/shock' style.
    No leaf springs, no standard shocks

    No TAB is designed for rough road driving.
    Boondock is the lift and marketing.

    Is there any way to soften the blows of standard interstate bumps?

    Don’t over inflate your trailer tires. I keep my 400 BD at 50 psi, which seems about right.

    you could replace torsion axle with Timbren independent axles

    Trailer tires have stiffer sidewalls to help carry loads and reduce wobbles. Switching to truck tires that have the ratings to carry your trailer will give a softer ride. If your tire size starts with the letters "ST" you have trailer tires. Truck tire sizes start with "LT." I have LT tires on my trailer it still bounces a bit so this may not cure your issue entirely.

    Curious and looked these up. Like the idea on an actual structural steel frame such as my construction trailers.

    Without a cross axle to help stiffen the dismayingly flimsy sheetmetal C section frame on the Tab I'd worry about serious frame distortion.
     Our Tab has exhibited torsion flex and heaved floor and cabinets as it is.

    I've thought about fabricating a full length, structural subframe with rear bike carrier hitch.  For the work involved might as well build out a cargo trailer as camper.
