I'd try one of the various brand specific owners groups or forums. Only be aware some of the brand specific groups are monitored by loyalist gate keepers so negative commentary gets quickly gaslighted or buried. AI reports the HR 34 mid-bath model on the f-53 chassis is notorious for front grill issues where the grill collapses due to wind force requiring a $1000.00 fix. The large bunk bed or living room slides are reported to jump tracks or fail to fully retract ( Large 12+' slides on the f53 chassis are however notoriously unreliable regardless of which RV brand). Owner's often rate the post-purchase experience poorly citing long wait times for repairs at dealerships.( Keep in mind an RV dealership does not operate like a new car dealership, only the dealer where you bought the RV is obligated to perform warranty service, in many cases other dealerships are going to refuse to service an RV purchased elsewhere). Know too, that unlike a car dealership, service for an RV dealer is a liability not a profit generating arm and in light of the fact an RV dealer is 1st cousin to a used car dealer lower your expectations, ordinarily to very low.
