best bike rack

Would appreciate any suggestions for a good 2-bike rack for our 19-foot PleasureWay. There is no ladder, but there is a spare tire on back to the system would have to extend out a ways or be configured to attach to the spare tire in some way. Any suggestions and names of manufacturers would be appreciated. Thanks.

I have been really looking into this and have come to the conclusion that the ones that hang the bikes by the frame are suseptible to allowing the bike to come off (altho this can be reduced/eliminated by a good tethering sys) and also after following a few rigs with the different types, I'm leaning toward the ones that hold the bikes by the bottom of the wheels. The bikes seem better supported. Go to the web site and you can get some ideas including some useful reviews.
