I had the power jack on my former TT and would never be without it...
On my new 5ver I have the slide toppers and with leaves, pine needles etc for me they are a definite on all future campers..
I prefer the aluminum wheels compared to the upkeep I had on the steel wheels on my previous 5th..
This is my first camper with power rear jacks and I love them... Previous campers I used a Harbor Freight rechargeable impact wrench to raise and lower.. also came in handy when changing tires...
The DW would not be without an oven.. She loves to do lasagna, bake cookies, cakes, brownies, etc.. She bakes more in the camper then she does at home...
But in the end it is all about what you enjoy.. And you'll find that your needs/wants change with each camper overall
