Thanks for all the replies. Some handy info there.
The reason we are considering it is that due to work commitments (Shift work, Holidays etc, Paramedic), we cant get away as often of on the usual days of normal people. My wife also is not a good camper. So, we want to buy a decent one but don't want to have that much value just sitting, collecting dust.
If we can get it rented out a bit, the CT will help pay for it self. Especially if we wont need it peak periods.
Really appreciate the info. Especially Mark (McGirr). First hand knowledge. Greatly appreciated.
