Attach an eye hook to the wall and use it secure the tie when you need your curtain to stay open. Any lightweight bungee will do the trick, unless your curtain is exceptionally heavy. We found the 3-pack from the Dollar Tree works fine for ours.

If you're temporarily using a portable toilet in your RV, you know it may shift when driving. To avoid accidental spillage, secure an eye hook to the wall behind the toilet on both sides. Then, attach a bungee. Be sure to leave space to use your flush handle, if you have one. The thicker, rubber ones are best to use in this instance, as they tend to hold more weight. We spent less than 2 bucks at Home Depot getting one that works for this. Our portable toilet is a Camco 5.3 Gallon.

We used a long, thick bungee that was about two bucks at Home Depot to secure the bathroom area before we fixed it. This helped while driving because it prevented everything from flying around. This is good if your bathroom (or another room) is under construction, like ours was. It also helps if you have any other area where there may be loose furniture or other semi-big items. The bungee held in a portable washing machine, a baby gate that kept the toilet secure, and a few miscellaneous things that were tucked around those items.

Your wall shelves should be secure, ideally. But if you want some extra protection, try using a bungee cord to secure the shelf even further. We often do this if we want to place something on the shelf that might otherwise fall while driving. It could be a book someone is reading here and there or something else fairly lightweight. This isn't a good solution for heavier items.
(Pardon the sawdust in the picture. This was taken right after setting up this particular fix.)

Since we are in an older motorhome, this is a common problem, as we are under construction. This is a good temporary fix if your existing hardware isn't the best or you are missing the latches. In our case, we just needed to fix the latches. We don't need to use this anymore. But it worked to keep items from flying while we awaited delivery of the appropriate hardware. The simple Dollar Tree bungees were fine for this as well.

When we were doing a lot of work on our vintage RV, this one helped a ton. We kept a Homer Bucket from Home Depot full with all kinds of tools and hardware that we were using every day. We didn't want to have to keep putting away and taking out these items every time we had to drive somewhere. So, we kept it secure with a bungee. The Dollar Tree bungees were fine for this as well. But remember that the heavier the item, the stronger the bungee cord should be.
8. Tie Down Luggage - This may seem obvious, but not everyone thinks of it. If you have extra luggage that you don't want stored inside, try securing it to the roof with bungees. Heavy duty bungees should be used for this.
9. Secure an Infant Stroller - If you have a large infant stroller, like our Graco double stroller, you may not want to store it inside your rig all the time. Unless the weather is bad, we prefer to bungee ours to the cargo carrier luggage rack on back. That way, it's easy to grab and then store when going in and out of stores or entertainment facilities. This also works if you want to store the stroller inside because you may not be able to fit it inside a closet. In this case, you can bungee it to keep it from roaming around your RV.
10. Secure a Cooler Full of Groceries - If you just picked up a bunch of groceries and want to wait to put them away until you get to camp, you can throw them all in a large cooler and secure it with a bungee on the roof, in a rooftop cargo box, or in a cargo carrier.
