1) Typical trailers are not "designed" for full time living, you can do it but things may require a lot more repairs. There are TTs which are designed more for full time living but they tend to cost much more.
Many Rvs are not well designed for WINTER LIVING, this can be a real headache if you are dealing with the likes of Alaska or even some of the Northern States during the winter. Water systems can and will freeze up easily, furnaces are not very efficient and you could expect to use a 30lb cylinder of propane in a matter of a few days.
2) quite subjective and very hot subject, I will allow the weight police tackle that..
3) Things happen anywhere, campgrounds are no exception. While most "campers" are pretty friendly and easy going but it only takes one rotten apple to spoil things. (I have had the pleasure of a team of drunken rednecks partying until 2AM every day for a week).
Campgrounds CAN and do get noisy during daytime hrs (kids screaming and having fun, cars and vehicle traffic not to mention the folks who are showing off their megawatt stereo systems in their vehicles for hrs at a time and so forth), something to think about if you get stuck on a night shift and NEED to sleep during the day.
Campgrounds vary in availability and it may be difficult to locate one near your assignment each and every time. Not to mention many campgrounds in cold climates will close for the season further making it more difficult for you (I don't know of any around my area which stays open past September).
As far as break ins goes, well it can happen, folks have lost generators over the years I have been visiting this forum. For the most part it is common sense, don't leave valuables in plain sight and hopefully no body will mess with the trailer.. For you 12hrs of no one around daily "could" be a tempting invitation for an unwanted house guest.
4) Varies a lot, some campgrounds get extremely busy "in season" and will require an advanced reservation of months or even a year ahead and those may require a weeks stay.. 13week stay might be doable in one place and not in another..
Price can vary from $20 upwards of $100 per night depending on location and if it is a State Park or a private "resort".
Electric, water, sewer, cable, phone service all varies from none to full with State Parks leading the way for pretty much nothing, no hookups to if you are lucky one with some electric and water. If you want full hookups you will be ruling out State Parks for sure (you will not want to work in VT their state parks do not have ANY hookups and the use of generators ARE FORBIDDEN and private parks are very few).
5) New or used?
Used you can find trailers for a few hundred up, new, well the sky and your pocket book is the limit..
6) Personally if you are attempting to save money, forget about a RV.. For a new TT you can expect to spend $20,000 and up then you are going to pay per day for the campground, plus your laundry, food, PROPANE ($$$), some campgrounds also meter the electric service for long term campers on top.
I think you will find the cost of owning a RV will exceed the cost of hotel lodging unless you are planning to be the minimalist using candles for light and heat and plucking your meals out of a river..
I wish you good luck..
