Well from the looks of the U-Haul website, their motorcycle trailer doesn't look like it'll get the job done with 2 bikes since the Max load is 950lbs. Two of our bikes are over 1,000 lbs. All is not lost though, because they have this open trailer with ramp with a max load of 1,650 lbs. But that one does come with heavier restrictions on the vehicle towing the trailer.

Putting them both in with the front end first shouldn't be a problem. I don't know what kind of tie-down points that trailer has, but in general it's a good idea to tie them down from a low point on the bike and also up high when talking about the front end. If you only tie from say...the handlebars, the bike's front wheel could slip out.

Good luck, and btw...I mailed that magazine today.
