Securing stuff in a fifth wheel while underway
I use the shelf liner like in the link above for the kitchen cabinets and have never had anything shift, although we do have a central kitchen. I have an almost finished roll of paper towel I run better the wine glass stems so they don’t flop over.
I have 2 sets of glass door cabinets, the one having electronics, candles and other small items. I have soft side baskets from the dollar store for keeping things separated and safe.
There are plenty of good tips here on how to keep your things safe from breakage or from moving around, but one very important factor with any 5th wheel is weight and especially weight side to side.
Once you have everything into your 5th wheel, fill your water tank (especially if you fill to go boondocking) or at least fill to how ever much you may typically travel with. Have your propane tanks full and fill the fuel tank in the truck. You want to weigh with the maximum you will carry.
At the scales weigh the front axle of the truck, the rear axle with king pin weight on it, the RV axles and weigh each side of the RV. Some scales may not be able to do this, so find one that can. We flattened springs on the drivers side of ours once over a big pot hole outside Denver and again over a nasty overpass on I-10 in Louisiana. When we finally weighed side to side, we were shocked to learn we were 900 lbs heavier on that side than the other!
Now, when we travel, we move inside stuff from that slide and stow on the other side. That slide has the two recliners, a free standing end table, stationary bike, and a few things tucked behind a chair. All but the chairs get moved over to travel.
The heavy side already has the batteries, Xantrex inverter/converter, water softener, and fridge stove, furnace and water heater, so we stow any other heavy stuff (totes of stuff, golf clubs, our three 5 gallon jugs of water) on the opposite side to displace some of that weight.
Many blow outs are very likely from a weight problem as well as all the other factors surrounding tires. We run a 14 ply tire and have not had any failures in 7+ years and 80,000 miles on the 5th wheel.
Weighing will allow you to be sure you don’t have too much king pin weight in the truck, that your combined weight does not meet or exceed your truck’s GCVW, and that you haven’t met or exceeded your RVs GVW.
