Hi Sharon:
Welcome to the group. An excellent choice of year if I do say so myself.
You should tell us what model it is. You mentioned a single axle, so it is
no larger than a Safari 22, perhaps a Globetrotter 20, or maybe a Caravel
17. As for the toilet (s): one would not be difficult to reinstall (2
flange bolts to hold it down - water is an option) but since you are from
the chilly NW there is a chance the water system was frozen at one time.
Proceed carefully and slowly and check it for leaks.
Re: '68 or '69. This '67 you have is nearly identical to the '68. The
models changed considerably in '69.
Have fun and good luck with it,
