It's not the diesel side of the generator that needs exercising, it is the electrical side.

I would think one of the exhaust hoses that mechanics use would work. if they don't cause back pressure on cars, they shouldn't cause back pressure on generators.

Straight from page 10 of the Onan generator Manual.

Exercising Your Generator
It may seem surprising that “not” using a machine could cause performance
problems, but with RV generators that’s exactly the case. Regular “exercise” is
an important part of keeping your generator healthy. Lack of exercise can cause
moisture build-up and fuel system degradation that make it run poorly. In fact,
in as little as 30 days, the fuel in gasoline-powered generators can begin to gum
and varnish the fuel system. Fuel varnishing results in hard starting and surging. (A
surging generator never settles at a stable operating speed.)
To prevent such problems, it is recommended to run gasoline generators at a
minimum of 50 percent capacity (2000-watts, or one air conditioner for a 4000-watt
set) for two hours once every four weeks. This is necessary to help keep moving
parts lubricated, expel moisture and control fuel varnishing in the carburetor. A long
two-hour exercise period is preferable to several short periods. While traveling, this
can be accomplished by running the air conditioning. If you own a diesel generator,
regular exercising can help reduce internal condensation and helps keep seals
lubricated.

I'd let it sleep.

You post info supporting exercising gen with reasons why and then recommend NOT to do so :H

OP......
Ever seen a Gen-turi exhaust system? Used to get the exhaust from generator up/above top of RV.....same type of thing could be done and run it outside your garage.
The extended exhaust pipe does not connect directly onto gen exhaust pipe so back pressure doesn't occur.
