I think it would be a very tight fit and may make access to the inside near impossible. I can imagine it would close off the fridge, the kitchen area, the bathroom door (which swings into the kitchen area) and therefore the bedroom. There was one person on the forums a year or so ago who did the original mods that inspired me on his 25RR and I thought he loaded 2 bikes at times, one behind the other. His handle was Night_Wolf and his blog was called Pimp my 25RR, but I haven't seen anyone else load in 2 large bikes.
My BMW F800GT is not a big bike but in the 26RR trailer it grows bigger! The 8 foot width is in reality only 7 or less when the seats are folded up. I would get a measuring tape and do some measuring of the insides and the bikes and make sure you allow for chocks and straps. See what you think then.
