Do you switch the transmission into nutral, step on the brake, and wait for it to switch? If you have an auto tranny, it will not shift into low without the gear in neutral and the brake pushed.
You also don't normally need low for backing a trailer
4H is usually more than fine.

What is this low lock you speek of. I have not known a t-case to have a low lock since the 203.
The above procedure should work.
Now as far as backing up large trailers, many SD owners will upgrade the stock ESOF hubs, and install manual locking hubs. This permits the use of low range without locking in the front end. You can achieve 2wd low range with this method. Often times the lower range helps when traction conditions do not require 4wd.

I can get my SD into low range w/o using the brake, but you HAVE to be in nuetral.
I use 2 low in the '79 to back up the camper all of the time, barely have to use the gas with the extra gearing.
