Wow, Can the 2021 Grand Design Solitude Handle 114 Degrees?

One of the biggest problems living in an RV in the desert is staying cool. Most RVs simply lack the insulation and AC systems to handle temperatures as we are seeing in Las Vegas. Every manufacturer claims to have great insulation with R numbers flying all over the place. Having owned 13 RVs I was skeptical about Grand Design's claims about their Racetrack ducting and new RV Airflow inserts (the device optimizes airflow).
