I would use a decent low loss coax, a remote relay box, and keep the tuner
in the shack.

I'm thinking of mounting a tuner up on the tower to feed the 160 half sloper
(single wire) as well as the 75 meter fan dipole and 40 meter sloping dipole
with ladder line, so I'll need to add a few relays to switch antennas.

This can be a simple manual tuner, remotely driven with air variables and a
switched inductor, or vacuum variable and a rotary inductor, or even one of
the MFJ 998RT auto tuners. If I build it, I'd much prefer a tuner that
handles single and parallel wire without using a balun

Unfortunately the 998RT only has a single wire and coax output. I can work
around that and *apparently*, or at least some think it'd handle all the way
up to 2500 PEP.

Of course there is the problem with lightning and remote tuners mounted at
or near the top of the tower.  Grounding relays could be added.
