We bought our 2015 Thor Challenger 37GT in May of this year. Brand spankin' new......It is back at the dealership for the 4th time since we bought it for "warranty work". We have had multiple, multiple problems and this time the front windshield had a water leak or shall I say "pour".....I guess my question to you experienced owners of "new" motorhomes, is it normal to bring a brand new rig back in for so many warranty problems? It's like we get it home and find something else....The dealership does the work without any questions, but it's usually between 4-8 weeks before we get it back...We try to wait until we get a list of problems before we bring it in, but the water leak couldn't wait......I'm really getting frustrated with the whole process...This is our first motorhome....
