Unless the satellite system includes a real sat dish, not just a crank up, and a receiver, and the solar is real solar panels and a 3 stage charge controller, they are just something. Check the blue book value of the MHs. You will find the listed items are actually standard equipment, and included in the base price. Look at Kelly Blue Book prices and print them out and take them with you to the dealer for the final price work. Everyone will tell you what you should pay, but only you will know what it is worth to you.
Good luck
