On our last travel trailer, we switched from load range C to load range D and enjoyed the extra margin of safety. The C LR were right at the trailer capacity and I like some head room in capacities.
I can't comment on the AL-CAN HWY, but on my old TT I changed tires for the same reason as Hawkeye-08. The original C-range tires actually totaled LESS capacity than the trailer GVWR. The manufacturer was relying on weight transferred to the truck make up the difference.
Even though I always kept the tires at 50PSI it just always seemed like the sidewalls looked squishy. When I got new tires I went up to D-range and it was a night and day difference. The sidewalls were firmer, I have plenty of extra capacity, and it felt like the TT towed easier too.
If your wheels will support 65PSI I'd say go for it and give yourself the extra cushion.
