LOL, I am not surprised why you are asking, given what we had to do last time with the van…:lol:lol
Yes, I do have a set of tie downs myself. 4x7 will be a tight fit.
If Vlad decided to go, we will need two cars anyway, so it might be better to tow your triumph like you did last time with a proper bike trailer.
Otherwise, going one size up from 4x7 to 5x8 should do the trick to fit 2 bikes comfortably.
Vlad, will you be trying to fix the SV so you can make it?
