What size would be needed 100A or 200A?
200A - you want the isolator to be rated for higher amps than max charging output of alternator.

If you install a Perko manual switch instead of the isolator, is there a need for the boost solenoid?
Not Brett, but here is another possible setup.  I replaced my boost solenoid with a magnetic latching solenoid.  You could replace the isolator with this Blue Sea solenoid instead of the manual Perko, and thereby retain full control from the driver seat.

Yes, diode-based isolators are still available-- certainly not a Foretravel-specific item.
But other work arounds: Battery combiner
Manual marine ON-OFF switch with alternator B+ and chassis battery to one lug and house battery to the other.
And, of course short term work around is to combine wires from B+, chassis and house battery on one lug. Be sure alternator sense wire is also to any location directly connected to the chassis battery.

You have read a lot of good suggestions and gotten a lot of good advise. You can keep what you have in terms of operating capability or modify your coach as other has suggested. There is no wrong way to go with these. Just need to think through what works best for you and is within your budget.

Anything manual has a percentage chance of either not working or not being turned on correctly

The blue seas combiner  is almost foolproof.  In our case powered by roof mounted solar.

All new coaches use an auto combiner
