best not to strap down from the bars, and leave the kickstand up, if something happens and its down and breaks off you got nothin. strap down from the cross member, not the bars!!! straping down a dirt bike or small bike from the bars is ok but not a bike of this size or bigger, its possible to damage them. good luck!!!! i would drill a hole in each corner of the floor, get me some eye bolts and some fender washers(one under the floor and one topside for each bolt) and strap er down, when you get there take the eye bolts out and return the thing, they will never notice and if they do.....deny, deny, deny,....those holes??? they must have been there when i got it????? but they wont notice, trust me, if anything, they might look inside to make sure its clean, but thats about all. and hey!!!! did you measure the inside of that trailer??? sometimes 8' is not really 8' inside and you will need 8'
