I suspect you are experiencing rattles, bangs and squeaks as we did with our Bessacarr. Our first step was to reduce the tyre pressures to 58psi all round. Second step was to fit buffer pads to doors and drawers. Third step was alter the locking mechanism on the oven door which was so badly fitted I could fit my fat fingers into the gap at the top of the door. Fourth step was tighten all brackets that secured the table and tv whilst in storage, Fifth step was to put felt between all the pots and pans, Sixth step was wrap the utensils in towels. Seventh step was to secure everything in the lockers so there was little to no movement.
All of the above worked but the biggest improvement was fitting air suspension.
Good luck.
