I had a Lance Squire 8.6 before I got my currant 9.6..The bathroom is just a little bigger,not by much but alot more room and storage..We looked at a new Adventurer 89RB in Lewiston ID when we were there..The bathroom was huge compared to either of my two latest Lances...I was shocked and did not expect it to be as big as it was but then you jump up to about 2600# where most TC's start and water capacity is like 42 gallons or so.
Adventurer TC's has three models at 2K or less but they have less water capacity...
The Adventurer 86FB an 89RB both would fill your needs but a little heavier..I would have put either on my F-250 and called it Max.
