It might be a closer call if you didn't already have a Class A that you are familiar with. Or if you were going to sell the Class A and buy a travel trailer. Honestly, I think you would be happier if you were both comfortable driving the Class A with a toad. I would work towards that goal. I grew up on a farm driving tractors pulling large farm equipment; also pulling horse trailers.
Driving our 40 foot Class A with a minivan in tow is much less stressful than pulling a trailer. For one thing, you know what is moving around in the Class A while you are on the move. With the Travel Trailer, you have to wait until you get there to find what you forgot to secure before departure.
Throw in the convenience of the onboard generator and not having to leave the coach in the rain. Plus you don't have to move your electronics from the trailer to the towing vehicle. Basically everything is right there with you in the coach.
