Thank you very much for replying! Yes, they both seemed very similar in person as well. We did sit in both (dry), also felt similar. The prices were approximately $500 apart. The Saratoga dealer did say the full insulation was included. We are a family of 4 that would be using it - 2 adults, 2 kids. Both dealers have very good ratings and have been around for awhile. Do you feel the Caldera is a good quality model? Are the jets strong in the Vanto? They seem overall smaller in size compared to the Saratoga. Also, the jets all look to be the same type on the Vanto. There are a variety of sizes and types on the Saratoga. Does that make a difference? Thank you for all of your help!!!! Any input is helpful!
