to the forum and congrats on your new tt.
As far as I know, all the LaCrosse tt's come with the RV version of a queen bed. The only models we saw that had room at the foot of the bed were the 301RLS, 303RKS and the 305RES. They are coming out with a 308RES and I believe it has room at the foot of the bed as well.
I know this doesn't help you with your problem, but since the bed is up against the wall I don't know of anything you can do.
Good luck.
