Was wondering if it would be a problem if used a 110 line for my shore power for a sort time in transit? I have a plug that has a 110 receptacle and the typical shore power mate on the other?
 
We do it all off season when the boat is on its trailer in the driveway. Just make sure the 110 volt source can deliver at least 15 amps. And that the cord you are using between boat and 110 volt source is good for 30 amps.
We use our normal shore power Smart Plug cord and a short Marinco pigtail adapter at the house plug side.

My boat is on a trailer in the driveway right now and is powered by a 110 pigtail I made for my shore power cord. You just have to keep in mind the amp limitations of such a set up and manage the load. For example, run a battery charger, refrigeration, and lights. If you then want to use the water heater, turn off the battery charger while the water heater is in operation.
 
Assuming that everything has the correct circuit breakers installed (15 amp) there should be no concern with running a 15 amp extension cord to your 30 amp system on the boat. The only problem is, if you over load it, then you will pop the breaker. And that is pretty easy to avoid if you make sure to only run one heavy load item at a time.

What you want to avoid doing is using an adapter on a 30 amp outlet and plugging a 15 amp extension cord into it and then running your 30 amp system over that. In that scenario the 15 amp extension cord does not have the correct current protection. When I see people at the dock doing this it makes me cringe.

Thanks, I have the same pigtail for another trailer, just wanted to be sure it was OK for my Tug.
