Oh my, to answer this could start the nosewheel debate again so I'll be careful. I used to be based out of Frazier Lake and absolutely loved it. The field is great, the people are great, and life was wonderful. It was there where I had a problem with my nosegear while parking. Recognizing however that the grass runway is very well maintained I still land there if the need arises. To answer your question there are "A" model RV's based there and have had no problems that I am aware of. The overall experience of "Aviation" is better at Frazier Lake than any other airport I've ever been to. If you can get in you will like it a lot.
Edit... Just noticed that you are building a tailwheel plane. There are several tail wheel RV's based there and do just fine. Really, Frazier Lake is a family. You will love the atmosphere.
