It’s another way to skin the cat but it’s a poor way except maybe in the case of long term storage with solar maintainer already wired into the house setup.
Makes no sense to continuously draw from and cycle the house batteries, shortening their life, to charge the start battery.
I don't know about your DCDC charger, but the old Trik-L-Start didn't pull any power from the house battery unless it was at, at least, 13.2v. In other words, it didn't pull from the "battery," it pulled from the converter/charger charging the battery.

If not doing the above just plug in a 120v battery maintainer and keep ‘em separate.
Hence my original suggestion. Permanently install a 120v trickle charger and hardwire it to the breaker panel in the RV. Automatic and permanent.
