I am putting up a single DXE 80m 1/4 vertical. I can put out the proper radials. I will have to add some longer ones for 160.


That's a good vertical, and the 80M radials will probaby be adequate if you have enough of them.

Now to figure out switching in and out 160 and the matching.



That is always the difficult part. If you have a good ground system and high efficiency, voltage can get pretty high when on the higher band for a top wire, and the lower band for switching a coil. Many systems work at high power because of losses.

If you just want to run outside to change bands, it is easy.
