My old rig was not a Grand Design, but another manufacturer who was proud of their "full 12" I-Beam" frame. I was running 1,000 lbs. over GVWR and maxed out on axles (7k axles). After 2 years of fulltiming, I ended up having a buckled frame.
If you're going to upgrade the axles, I'd suggest that you also upgrade the cross-member supports between the axles.
And regularly inspect the suspension and frame while using it.
I trust Grand Design's answer. I specifically asked them if the chassis could carry the extra weight and they said yes. The folks staffing that line really know their stuff. They aren't generic customer service reps.
That said, the dealer is going to double check that nothing else needs to be upgraded. He said the springs might need to be upgraded. I also asked him to look into the suspension.
