Keep going to shows and walking through rigs; what works for others may not be your cup of tea. Sooner or later you'll land on a rig; then go after that one :)
My input
When we switched to a TH we had the idea that we would be loading everything in the garage every time. Now that we've been through two summers we've figured out that 99% of the time we put the atvs / side x side / bikes / whatever on the truck and not in the TH. Frees up more room in the TH for 'stuff'.
If I only hauled bikes I would have gone with a non TH 5er and put the bikes on the back of the truck; I can do 3 on the back of the truck in my sig. For a 5th I really like http://www.forksrv.com they make some very very nice 5ers or TH's; they do both.
