I recently purchased my first TT. I got a heck of a deal on a used 2008 G2 27BH. The trailer is clean and in very good condition except the tub is cracked.
It had a huge patch of silicone over the damaged area. I suspected additional damage and a must be replaced scenario in my price negotiations so I have lots of room to deal with whatever. I purchased a replacement tub/shower bottom online and it arrived yesterday. I will be doing the repairs as soon as time permits. I will keep you posted as to my progress and what surprises I might find once I get the old tub out. Here is a picture of the tub with the silicone removed.
If anyone has been down this ugly path before, feel free to share your experience and advice.
