Hello, I have just purchased a 1960 T-20 20' Avion travel trailer.I cant find the gross dry weight anywhere in the documentation. Can anyone help? I was thinking of towing it with my 1993 Toyota 4x4 xtra cab with a 3.0 litre v-6 using the hitch attachment that bolts to the frame and the sway attachment on the tongue. Is this an adequate/safe set up? Any info would be appreciated.
