Darmis,
I'll offer my opinion... and remember this is just the opinion of 1 person who owned a TM for 3 years and traveled over 16,000 miles with it.
The 3124King certainly has plenty of amenities that lend itself to living in it for extended periods of time... However, remember, TM is manufacturered as a "vacation" trailer, not a "permanent home." When you compare "vacation" trailers to the "higher quality" units intended for full-time living, you'll find substantial differences in the way the trailer is built and the quality of products used in them. Check the RV Rating Book [
www.rv.org] definitions of the various "levels" of trailers to verify my comments.
For us, the shower was inadequate to qualify for living in the unit for extended periods of time more than 1 week. Since all TM's use the same bathroom/shower setup, no matter what size the TM is, I think you'd find it inadequate for full-timing... remember, this is just my personal opinion.
