We don't own this one, so I can't answer all your questions....
We have lived here for 4 years now, though, and it was manufactured 2002. It is a Liberty home 16' x 80' (singlewide) 2 bedroom/2 bath with a sunken kitchen.
When you come in, at first appearance, it is really cute. The kitchen appears spacious, and the living room is nice and big with a fairly large "entertainment center" built in. The master bedroom is large, with 2 closets (one is sort of walk in), a garden tub and standup shower. The second bedroom is tiny, barely holding a full size bed (which is a short futon style bed that folds up, so it isn't even standard bed height, if it was, it would make the room feel SO much smaller!), and the guest bathroom is nice with the toilet and shower being behind a second door, which makes it nice for guests.
However............. After you live here a while, you begin to notice how cheaply made the house is. ALL the "wood" is pressboard laminate. The ceiling is "vaulted" so that it gives the impression of extra height. Reality is that the lower edge of the wall is only about 4" above the top of the door frame. The peak of the ceiling is higher than a standard 8' ceiling, so it gives the impression of extra space. As the house has settled, it has shifted, and some of the windows do not seal well, nor do the doors. We are in a fairly secluded area, so we don't feel the pressing need to lock the back door religiously, and its a good thing because frankly it wouldn't matter, the house is just plain not secure.
At first look, the kitchen seems big. Until you start trying to organize in it. All the cabinets have deep edges that prevent you from easily using the space inside, the width of the cabinet and the width of the cabinet doors are not the same, so there is a LOT of wasted space. The cabinets are also awkward, with deep corners not being used efficiently.
The "mud room" at the back door is also the laundry room, which means if you live on a farm the dirt is tracked right past the washing machine coming in the back door, and so heaven forbid you drop anything from the washing machine into the dryer, or out of the dryer.
It is also tough because NOTHING in the house is standard. The framing in the walls isn't standard, the appliances are off brand no-name companies, the parts for the sinks and spigots aren't standard measurements, everything is unusual.
The biggest issue we have with the house has to do with the outside. The house does not have eaves or gutters, so when it rains, the water streams straight down the outside walls. Over time, it has worked its way between the siding and the wall, and now leaks in the windows. I have to keep tubs in the windows with rags perched everywhere to catch the drips, and sometimes streams of water coming in. When I can't catch the water quick enough (if I'm not home, or for whatever reason), the water lands on the window sills, which are only pressboard, so over time they have swelled and deformed now. The front of the house has a roof peak over the front door, and at the point where the peak comes down to meet the straight roof line, the water runs down the wall in a more concentrated amount, and so in that area, which is on the outside of the wall where there is a desk in the kitchen, the water is actually coming in on the floor. The barn manager, who owns the trailer, has known about this since we moved in. We have always kept telling her how bad it is, and she just hasn't done anything. She is FINALLY putting gutters on the house this week, so we will see if that corrects any of the issue now that it is so far along. I suspect the house would be ok if she had done this a long time ago, but she decided to be in denial and ignore the problem instead.
I don't know what she paid for in the house, but I guess if you've GOT to have something mobile, then its alright. But if you don't need the mobile quality, then it is MUCH more economical in the long run to go with something else. This house is just not quality made, and maybe some mobile homes are, but this one is clearly not. The info that we have seen says that these homes are supposed to last 30 years. I would NOT want to be in this house 15 years from now... I can't imagine what would need to be done to it to make sure it is still a good home.
If we had a choice and the ability to do it, we would build modular. Many modular builders build ABOVE what the required spec is for homes since the manufacturing cost is inexpensive (being able to 'assembly line' a product makes it much more cost effective and efficient!), and the home can be transported and then put up in a matter of a day, rather than spending MONTHS putting up a standard 'stick built' home. There is a house on my way to work that is going up, granted its a ginormous house (stupidly huge, I am so sick about it, the little house they tore down to build this one was beautiful... so wasteful!!), but it has been under construction now for MONTHS, I think since close August, maybe even earlier. A average sized modular home goes up in ONE day. Some friends of my parents have a modular, and when we visited them they showed us quite a few things. The roof is built of 2 x 6 boards, rather than the standard 2 x 4s. The construction is sound, and the home is beautifully made. You can order it as "nice" as you wish - granite counter tops, wood flooring, vaulted ceilings, etc etc etc.
. If I were to do it again, I would be buy a cheaper model or a good model that had been "kindly" used. 
We've done pretty good with just the fireplace (the thermostat on the central unit is set on 60 and only comes on in the middle of the night when the temps are in the 30s).
