1) You simply don't need a tailwheel endorsement to tow a glider. Temora used a Beagle for years.
2) Thus you can tow a glider with a tricycle undercarriage.
3) Gliders are by nature somewhat of a tailwheel aircraft so that experience counts.
4) Tocumwal in NSW have a Eurofox (RA-Aus) taildragger that also tows gliders and a Maule, (VH), last I heard.
I would suggest you ring Eddy Madden at TOC who will give you the best advice and probably organise some accommodation. (owns the airport caravan park).
