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.
The types of outbuildings that do have foundations, tend to have only a simple cement slab foundation, rather than the type that sits below ground level. For this reason, outbuildings can be constructed more inexpensively and faster than an addition to your home or a new building with an excavated foundation.
