First the bunk ladder:
The original cab bunk ladder Jayco supplied with my Seneca was very uncomfortable to climb in bare feet, even my young grandsons complained. I purchased an aftermarket RV bunk ladder from Amazon, it had wider rubber-covered rungs, but was flimsy and still hard on the feet.
I recently decided I needed to do something better. So I sourced a "shelf ladder" from Amazon which is somewhat like half a stepladder. I then fabricated two adapters out of 1/8' steel stock. I riveted these adapters to the outer beams, and the top of the adapters were heated and bent to form hooks for attaching to the existing bunk. I then painted the whole ladder in black textured finish.
New ladder is very sturdy, no deflection at all. And the rungs don't hurt the feet! I still may cover the rungs in carpet so they are not are not so cold.
Here is the Amazon link for the ladder: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Now the vacuum:
I also finished installing an Intervac central vacuum system today. I located it in the the void space in the sink base on my TS. I had to slightly modify the cabinet below the sink, but that cabinet is relatively useless anyway. We haven't found anything to store there so far, maybe just spare vacuum bags for now! Should make cleaning up easier than messing with the portable vacuum we use now.
