I would buy the Dakota Traveler at that price every day if it’s length of pull is close you yours. Get a scope with quick detach mounts for each barrel. If it fits you and in good shape, the $6000 is a great price! Use the .375 H&H barrel until you have your dangerous game animals in the salt and then switch to the .300 H&H barrel for the rest of the safari for plains game.
If not the Dakota, I would do option #2.
