I learned this frugal little RVing tip from a good RVer friend of mine Eddie of Mobile Homestead Solar Services.
First, you pick yourself up a roll of plumbers pipe hanger strapping found in any hardware store. 10 feet of it goes for around 5 bucks or so. It’s a good item to have in the RV anyway in case of an emergency it can be used to secure something in place.
Then acquire an old worn out or leaky fresh water hose. Maybe check out the RV Park garbage bin, haha. A regular garden hose can be used but I think the white hose looks a little nicer.
Cut both items into desired length sections to build a hanger of suitable size for your application. Between the two of them, you should have enough raw material to make dozens of easy to use quality wire and pipe hangers for your RV mod and upgrade projects.
Not only is it cheaper than buying a bunch of pre-built clamps and hangers but you can quickly make up the exact custom size required. It’s also a great way to reuse/recycle an old RV fresh water hose.
