reducing weight less propane tank

[marcus6701]

I have not been RVing long. Have two little girls (4) and (2) so my time packing and unpacking is crazy. I dawned on me this week end at the PA Grand Canyon that I do not need both propane tanks. I never go for more than a long weekend and we never dry camp where we would need all that fuel. Just some for fridg while on the road. I have (2) 30lb tanks. Full they are almost 60lb. I am removing one of the tanks for weight saving.
What size tanks are everyone else using? Anyone else in this situation?

Folks generally have two so that when one goes empty, the system will switch to the other. If you need to save weight, I'd toss both 30s and invest in two 10s, instead, to keep the functionality of two tanks.
