2017 Kzrv Sporttrek

We purchased this rv trailer brand new from Happy Daze RV in Sacramento, Ca. The manufacturer is KZ/Venture RV in Indiana. We bought it in Sept of 2016. We have had no issues with it in the 5 or 6 times we have taken it on a trip. I took the rv to have general maintenance done to the wheels and the mechanic found that nothing on the VIN sticker matched the equipment on the trailer. The axles, tires and rims are all undersized for this rv. The axles on it are 3500lb (tandem) the tires are 205 75R15 with 5 lug rims. According to the VIN sticker on the rv and the mfr, this trailers dry weight is 8300lbs and should have 4500lb axles, 225 75R15 tires and 6 lug rims. Because we have never needed to bring in the unit for any service or repair, the dealer and mfr are both claiming no responsibility for this dangerous situation. I almost blame myself for not checking everything when we bought it. But as a consumer, I assume everything is right especially on a brand new unity. KZ/Venture actually did a recall on an earlier 2014 model for the same reason. Undersized axles were put on a model which they said could cause the consumer serious injury or death. Yet, they are completely ignoring our situation along with the dealership.
