Just got a TT, overwhelmed by what I need to fill it :)

Do not try to see the future. Other than the basics, such as wheel chocks, sewer hose, water hose,etc., buy things as you need them.

When we retired, we spent $2,500.00 on what we thought we would need. One year later over 1/2 of the stuff was not even used once.

Go slow.
