How do I install horizontal propane tanks in my Lance 1161?

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 .:)
