My class A is a bath and a half model. THe reason for the half is you can not reach the main bath with the slides in less you climb over the bed. NOT a problem though as the half .. Has the needed half as they say. Another advantage of the half is "2 holes no waiting" and as you know the length of "a minute" depends on which side of the door you are standing on.
Major issues with slides can be dealth with easily
Accu Slide,m Inspect cables often and learn how to check the adjustment nuts
Power gear. I buy 1/4" grad 8 bolts washers and Nylock nuts by the dozen You need a bolt that is long enough the SMOOTH portion goes all the way through and you need to washer it up to make the nut tight.
That's about it .
