Thinking Kayakes (2) for wife and I. Not sure we will like them, think I would at least, not sure about wife., so do not want to break the bank. Start cheap if we like them maybe upgrade later. Definitely want roomy cockpit possibly small storage area.,Advantages/Disadvantages of sit on compared to sit in. It seems to a novice like me the sit-in would be more stable but sit on may paddle easier??? Have 13'3" high 5th wheel, thinking a rack on rear of 5th wheel. Trailer has 21/2 " hitch. Guessing 12' length max?? Any suggestions will help.
