47-59 New Garage Advice

[vintovka]

A little over 2 years ago i had a stick built garage built for the 54 (and an suv). 24x30. 10 foot walls, 8 x16 wide rollup doors, hardi backer siding and metal roof. With move i find myself having to build another garage to house the 84" tall 54. I found the single 16 foot door tight when opening doors and am looking at 26' wide with two 8x9s. May have to go with a metal prefab. Anyone have experience with one? Rusting both building and vehicle comes to mind. Will be for just parking and not maintenance or other car work. Should mention we are now on the river a half mile from the ocean. All comments, warnings and recommendations welcome.
