Thanks for all you're ideas. After going to the RV show in Sac with my wife, the only sort of TC my wife would settle for (space-wise for our 2 lab puppies) was the YA MOMMA triple slide out 11.5 foot land-yacht, that I would have to buy a F550 to carry. So, it looks like plan B, whatever that is. She liked the Lance 16' travel trailer. I was hoping to get away from trailers- I hoped maybe she might settle for something like this: http://uev.com.au/ - not that I could afford it, but mannnnnnn is that cool.
Anyway, the TC seem to be out of the picture for now.
A special thanks goes out to Jefe- thanks for all the great ideas.
Thanks for your help.
