Switch to vertical propane tanks

My old (sold) Lance had the lay down bottles (Manchester) as well. Never had an issue with them but I always considered them to be a bit of an oddity. You cannot exchange them, no one has lay down bottles to exchange and yes, replacement is expensive. Problem with converting to vertical is where do you put them. The storage area for a lay down bottle is smaller height wise, Probably the driving force in a lay down bottle, they take up less room in a TC, where room is already at a premium.

I guess if you were real industrious (pun intended), you could convert to a Hi-Lo style propane bottle (which are exchangeable) and are lay down bottles and are usually 50 pound bottles so a single Hi-Lo lay down bottle will have 2 times the LP capacity of the lay down (lance style, Manchester) bottles, and, the industrial hi-lo bottles are aluminum, not steel, so, they are lighter weight.

Unlike RV lay down bottles, Hi-Lo bottles can be used in either a vertical or horizontal position. However, I'm not sure if the deliver liquid or gas propane and if they deliver liquid, you'd need a liquid to vapor manifold in line as your appliances all run on vapor, not liquid. Hi-Lo engines have an induction system that takes liquid propane and vaporizes it.
