Recently purchased a 2021 Solitude 345GK. It has the G rated tires. On the Grand Design website you can download the brochure. Well this states the H rated tires are standard features (page 4). Well I inquire about this from Grand Design. It has been over 2 weeks and I still haven't received any correspondence from them other than an email on 2/6 asking if anyone has contacted me. I stated no and yet still no contact. Anyone else getting this type of "support" from GD?
