Hi, new to the forum, just purchased Class C Winnebago Vit 24P with Mercedes Sprinter chassis. Dealer tells me that rv issues will be handled by them and Mercedes issues including routine service will have to go through Mercedes dealer. Problem is, I despise the St.Louis Mercedes dealer. Rude, super expensive, hassle to get appointments. My question is, can I take my RV to any automotive shop for routine oil changes etc, without voiding the warranty? Shop I have in mind is Rick’s Automotive in Springfield, MO. They are authorized to service sprinters but can’t do warranty work. Any help would be appreciated, thanks.
