About feb 2012 the DW and i decided to leave our Condo and try the summer full time.
We bought a new 2011 29ft Sprinter feb 2012 used it for 4.5 months and once the DW realized she liked the RV lifestyle we traded the sprinter in for a 2012 fifth wheel 38ft xx inches with 2 ac units. 4 slides.
The sprinter travel trailer was nice but the fiver gives you room to strech if three years is the plan look for space get the most for your dollar and if its hot ware you live 2 ac units are a must my Sprinter had one,
And after the temps in the 90s the sun would warm things up in there.
If you plan on living in it full time, for as you say three years then i will asume it will stay at the same site year round. then you could get somone to tow it to your site if you dont have a pickup at this time.
full time for three years i recomend a fifth wheel 35 to 40ft
2 ac units
10 galion water heater
3 to 4 slide outs
king bed is a plus/ ours is a queen, invest in a comfy mattress ours was 975 from bedinabox.com
A camp ground with full hookups is awsome but if your trying to save $ stay ware its best for you.
We are in a stick house again but if we didnt have winters in Wisconsin i would love to stay in the rv, I cant wait to retire.
BEST WISHES AND GOOD LUCK
