Wheel balance, entry steps and W/D- 3 questions

[47hook]

Just dropped off my Alfa 5th wheel at the dealer we have ordered our MS 36TK3 from so he can get a head start in selling it. Our MS (#3787, if I understand the VIN #) is due in about 2-3 weeks. As I was getting ready to show the salesman my Alfa, he remarked on the electric entrance steps as a nice touch. I then looked at the MS's on his lot and noticed none had them.

Checking out the spacing between the tires to see if my Rotochok's would work (no, need to be modified for wider spaced wheels) I noticed that the wheels aren't balanced, like my Alfa's were.

We were going to swap our Kenmore stacked W/D from the Alfa to the MS, when the salesman suggested getting a new unit; DW thought that was a good idea, and so do I. We would prefer the units that DT puts in at the factory, the 2 seperate units with the roll out washer and dryer on a shelf.

Questions:
1. Has anybody changed the manual entry steps for electric fold down steps?

2. Anybody balanced their wheels?

3. Model #'s for the factory installed 2 unit W/D?

Any comments in these areas are welcomed. Thanks.
