Hi I am looking at a 2011 MPG 181 . the seller has said it has soft floors .But the water leak has been addressed. Unfortunately the trailer is over 3 hours from me so trying to decide if it is worth the time and gas to go look . How hard is it to replace the floors in this trailer ? Anyone with first hand experience ? It is not a especial good deal 10 K , but a new trailer like this in my area is 30 to 40K.Thanks
