A number of Glendale Titaniums used this arrangement and several owners needed to reinforce the bottom of the slide in the area of the rollers to spread the load. Without this, the load from the rollers caused some indentation and cracking of the bottom of the slide on some units. The modification was fairly impel to do - some 1/8" aluminium strips approx 8 inches wide IIRC, fixed to the bottom of the slide with CSK head screws. We had this arrangement on our 2008 Titanium and there were no problems. However, I'm not sure of the bottom of the slide in the BH Ti is the same construction as the Glendale Ti. You could try it, and if you see signs of damage starting, then do the reinforcement.
