I just purchased the XT 650 cottage,and the tub size is adequate.But I probably never will install the bench seat I wish they sold them without the seat/hardware like they used to do a few years ago.I just use a crate with a boat cushion.
Mine went together without a hitch,no problems with tight tent fitting.Some of the 900s/1200s had a problem with tent being too tight when assembled.
As far as lifting it into a truck bed,they can be bulky.I will make a set of crossbars to aid in lifting.
