On the other hand, in 2010, ice-out occurred April 5, and temperatures by the end of April were 50 degrees. My point is that the fish behavior around opening day depends not just on ice-out dates, but also on weather after ice-out.
You have to make decisions about the type of manufactured home foundation you want installed. A Low Profile type is popular now, but may be much more expensive. Generally, an alternative FHA approved pier foundation costs less. The Contractor will give you a bid on all the costs involved for either type foundation.
Modular and manufactured homes are not the same. Manufactured homes are not placed on permanent foundations. Manufactured homes, sometimes referred to as (but are not always) mobile homes, can be moved from one location to another. There are specific laws and regulations regarding these relocations.
