I use the Ancra originals. I haven't seen the red snappers. Are they rated for less or more pounds? If less, go with the Ancra Originals. Since the trailer you have looks like it has tie down points front and rear, your best bet is around the triple, as you suggested. I'd recommend the Ancra 18" soft ties, as the 12" will barely give enough length to go around the triple. In the back, I'd run softies through the passenger pegs, or somewhere in that area, one on each side, to hold the rear down. Don't tighten them too much, as you'll end up pulling the front wheel away from the chock. The idea is to just prevent the back from hopping around. Ideally, you'd want to pull both the front and rear straps forward, but that may not be possible depending on where tie-down hooks are on your trailer. Pulling the rear ones rearward will work as long as they aren't pulled too tight.
