Do you think two bathrooms in a 37-foot Class C motorhome might be a little “much”? Okay, technically, this is a Super Class C, if that matters.
Laura, who goes by That RV Girl on YouTube, takes us on a fast-paced and very cheery tour of the king-sized Seneca 37K Super Class C, which, as we have already said, includes his and her bathrooms for couples who do not like to share, or for family members and guests.
Laura begins her tour by inspecting all the outside compartments, revealing a lot of space for stuff. She then steps inside, where she moves from front to rear, quickly explaining all the features. You can tell she knows a lot about RVs because she moves through the RV with authority.
There is no “Consumer Reports” aspect to Laura’s tour. It’s all about hyping the RV, which, we admit, looks great. But we all know that beauty is only skin deep, which applies to humans and 99 percent of all RVs that have ever rolled off an assembly line.
Laura’s video is near the bottom of this article. So skip down to that right now or, if you have bandwidth concerns or a short attention span, then read highlights about the rig directly below.
OK, moving along…

Look out, Tony!
Very attractive sales rep and I love the enthusiasm! She puts a lot of energy into it! Jayco has built a fine looking machine here as well. The two bath is a nice touch, especially if traveling with kids or even another couple.
Honestly if it came with pantry and not the half bath in that space I’d buy it in a heartbeat. Living in these and always little kitchen/food storage. It sucks! Beautiful rig though!
Thank you for sharing the video and summarizing it, Cheri! I’ll not make a derogatory remark about Thor’s ownership of Jayco, but that connection does make me leery of Jayco products. Have a great week and safe travels!
