thanks everyone. Thinking about it we may not need a generator for a while.
We are planning 2 short weekend trips near to Asheville, NC where we live and want to try out the hookups so will have electricity.
Then in July we are moving to California and will drive our family of 5 and pet pig over to CA.
Given the heat and the fact we will leave the pig in the TT for a few hours sometimes whilst we explore an area, we will need A/C for sure.
We plan at least 2 weeks to make that trip over, whilst our household belongings are being driven over by a removal company.......
Then once we are in CA we may eventually require a generator if visiting some state parks etc. Years ago we rented an RV and went to Yosemite, but I think we weren't allowed to use the generator after a certain time, we were so cold that night (it randomly snowed!)
