2 bikes and a bed is always going to be tricky - but a lot depends on what bikes. 2x XL mountain bikes, then only a single bed is possible in reality.
2x Road bikes is a very different matter and probably doable in a LWB.
I have a SWB Caravelle and have a custom built interior which lets me have 2x full size mountain bikes (longest wheelbase 1350mm) with the front wheels off, and a single bed alongside them, and a full kitchen with sink/fridge etc.

Still here and enjoying the van, just life getting in the way!
