Trouble finding storage in Denver for 68 AS

[englishw]

I am moving from Texas to Denver next month and cannot find suitable storage. I have not winterized since I live down south and also have some leaks so I prefer covered. The most common issue is that many places won't take an older vehicle. I have been turned down by at least 4 places in the area. The other is the ones that will take it are very costly or not available because it's the middle of winter. Any suggestions would be greatly appreciated.

Thanks,
