Hiya Mike
Welcom aboard ..
In answer to your question .. yes!
Glad to be of some help.
Just kidding ..
Either bike will do what you want.
There are many guys here that ride two-up over decent distances with no problems.
I don't think the extra torque of the '05 Speedy makes a great deal of difference.
Many guys here with '04 and earlier Speedys have treid the '05 and not really noticed the difference ..

I'm totally biased but I prefer the America.
Comfy riding position straight out of the box.
I had other bikes as loaners during servicing etc and couldn't wait to get back to my wide bars ...
Good luck whichever you choose - you won't be dissapointed
