Type of new single wide in Texas - metal on metal, vinyl siding or hardiplank

I need to purchase a new home as a RTO at a park in Texas and trying to decide between metal on metal, obviously cheapest and allowed in my park but doesns look as nice as vinyl or hardiplank. Also, I have a few new vinyl siding homes in my park and they already been warping from the heat so leaning towards metal on metal for cost and withstanding the heat but wanted to see what is more standard or preferred. thanks
