Another alternative that would not require modification would be to go to 20# aluminum cylinders . This reduces the weight of each full by almost 20# , which can be considerable when lifting to shoulder height. IIRC you are down to WH and generator for LP usage . Don't have an LP generator so don't know what the consumption is , or how much you use it . If you dump at campgrounds most have LP so it may not involve to many extra stops . Just a thought .:)
I checked a reputable manufacturer of propane tanks (Manchester Tank; made in the USA), and the tare weight of their 20# aluminum cylinders is 18 lbs; the weight of their 20# steel cylinders is 21 lbs. There's not a significant weight savings, and the cost per pound saved is enormous ($30 for a steel tank; $200 for an aluminum tank).
FWIW, The typical use of aluminum propane tanks is for resistance to corrosion in marine applications, not as a weight saving alternative to steel.
