OK to stay hooked up?
When traveling from point to point, is there any downside to staying hooked up from the tow vehicle to the TT instead of unhooking? I'm just talking about for one or two night at most.

The only downside that I can think of is if you are on a sloped or not level site.
Also you need to make sure you don't drain your tow vehicle battery.

Unhooked you can adjust the levels of your trailer front to back....hooked you can't so make sure you're sort of level. Leave your power hooked to the truck but know that you are putting a drain on it. I've done it many times.

I do it with our 5th wheel quite often. If I'm reasonably level and want to get an early start the next day I like to stay hooked up.

I've done it with my TT in the past as long as the site is adequately level. Just don't get up late in the night for a Taco Bell run and forget you're attached

If level then why not. We generally unhook as we at least go out for gas.

As far as draining the TV battery, check to see if there is a relay that shuts off the feed with the ignition off. My '94 diesel is that way, no way to draw on truck batteries if the ignition key is off.

We do it frequently. If we are traveling and don't need fuel or go out to eat. I plug into the campground power, water, and sewer and leave the truck hooked up.
I sometimes drop the landing gear to steady the trailer up. Makes for a quick getaway the next morning.

Chuckster is right. Key off, truck battery out of the picture. Guess I was daydreaming. I do leave my vehicle on at times (running) to help the trailer batteries. I did drain all of the batteries (truck too) once by leaving the ignition switch on (forgot - 30 years ago).

Ok when the unit is plugged in to shore power it charges batteries. When tow vec. Is plugged into the trailer it charges the batteries from truck. If tow vec. Is wired correctly when hooked up and trailer is connected to shore power it should maintaine truck battery also

If the TV is equipped with a factory relay that disconnects the charge circuit when the key is off, it doesn't matter what you do with the trailer. My truck is wired "correctly" as that's the way Ford designed it.

I also do it quite often on a trip from point A to point B that takes a few days to get there. I have left the trailer on the truck and even put the front jack down and all the levelers. I turn the truck off and plug in the 110. Have not had a problem.
