Welcome and I hope your retirement comes quicker (time flies) than you expect.
I think we Eriba owner's can give you tons of advice etc. but probably you are best off thinking about your planned purchase, how you think you will be using / touring / storing your Eriba and then pop the questions in to us all.
When it gets nearer the time and you are actually looking at candidate purchases then don't forget to asking about "things to look out for / check etc."
Of course you can kick off with everything now and build up that knowledge base early.
One thing I would suggest and advise is the you will probably want a good year to acquire the best Eriba you can for your money which may take a little time. Also when you do retire you are "ready to go".
