I'm answering you because we have both the trailer and the Interstate and one thing you said in your message tuned me in. My husband and I both work, which means a set number of vacation days. We like to take road trips, and we like to go on back roads. If we are traveling and plan to stay in one place more than 3 days then we are more comfortable in the trailer. However, if we take any number of days but plan to spend them doing some serious site-seeing then the Interstate is our answer. Last year we spent 17 days going all over the State of Wisconsin - never more than 2 nights anywhere - and the Interstate was the perfect answer. Easy in and out everywhere. And, my husband is 6'4" tall and built like a linebacker. We have the twin bed model and he did great. He preferred the CG showers, but could do the Interstate showers if he had to. (Of course, when brand new I took the wall mounted soap dispenser off the shower wall which gave him a few more inches of elbow room.)
So, if you want to do a few days here and there it doesn't get any better than the Interstate. If you like to go to one place, plug in and sit and relax most of the time then the trailer is the answer.
Or, you could do what we did and get both. You only live once!
