If you have ever held a Class A CDL you would know that using an exhaust brake or "Jake" Jacobs brake when it is slippery is Dangerous and not to be done. Now rain is not, in most cases, so slippery as to affect your traction when the Exhaust brake comes on, however ice or snow is another matter altogether.
As a matter of safety and just good habit I leave the exhaust brake OFF when in a light "first" rain when the road is at it's slipperiest.
As for Tow Haul those above are correct who point out that it is a transmission mode switch only, however on my Dodge Ram 6.7L it does also DOWNSHIFT the transmission on it's own which has the same effect as the Jake Brake if things are slippery. (Especially ice or snow) You stand the distinct chance of rear wheel lock up. In Rain it is not so dangerous but is certainly a possibility.
Some of the above posts are good examples of a little knowledge being dangerous.
And since some of you will undoubtedly point out that I am new to the forum (thus what could I possibly know?) I have full timed for almost 4 years hauling my 34ft trailer to Alaska twice, once from the tip of the Baja and once in March (think still winter) and from Alaska to Maryland and back along the southern coast to the west coast and many many more miles. I have also hauled RVs as a "workcamping" job. And just for purposes of full disclosure I am not new to the forum. I have been here for many years but left in 2017 when I was working in Alaska for a summer and then spent this last summer in Europe. I am back now on the road again...
