Congrats on new 356qb. We just picked ours up 2 months ago and can't wait to use it.
You could get rid of the bumper grill and put your bike rack there.
I put a receiver on the front of my truck and put the bike rack there.
As for the tv, make sure you hit a stud. I would just mount the bracket to the wall and remove the tv when travelling. Also make sure the slide doesn't hit when bringing it in.
Look over everything. I have one fender skirt that was put on wrong and sits about 1 1/2 inch back further than it should.
Everything in these units is made for light weight.
Be ABSOLUTELY positive that all doors are closed when you bring in slides or you can damage them.
And yes, the fuses for the slides/remote are behind the large wooden panel in the passthrough storage. I cut a hole where the panel is to access it and made a cover.
I also bought a few cans of foam and filled the areas where the hoses and wires come through the floor. The holes they made were way oversized for what they needed to do.
Not satisfied with the stock switch layout here is how I changed mine.
