Hi everybody! Well, my husband got the electric rewired and it's working now. So the next thing is to get the propane tanks and get that going. Now I have question that might seem silly...but I truly need to know! Why are the propane tanks for a trailer so much more expensive than the the propane tanks we get at Home Depot for our barbecue grill? Can those be used? Is it the same propane? What is the difference. Thanks...Kate
