You've got a great SUV! I looked for over a year for a used garage queen 6 years ago before deciding to buy a new 2011 model. You should have no problem with any TT under 8k dry. If yours has the OEM round tube design, I highly recommend replacing with a Curt XD. The GMT800 pickup and SUV receivers often failed with less weight when they were less than 5 years old. Keep in mind your payload is closer to 2000 pounds with the 8.1L. 2700 pounds is about what the 6.0L models had available. Regardless, plenty for RVing.
How do you expect to camp with your RV? Always full hookups on paved sites? State and National Parks? Boondocking? 35-36' can be is no problem for most RV resorts, but site selection in Michigan state parks will be restricted. Do you plan to take bikes kayaks, or other large toys? Towing a TT with an SUV is challenging to take the those. Two adult and two kids bikes is easy now. If you intend to keep this RV for 10 years, then 4 large bikes will be harder to pack. You have plenty of TV to consider a toy hauler, even if you don't care about motor powered toys.
Bathtub is only useful if you have full hookups. You'll go through 40 gallons of fresh water in 2 days if you don't be careful.
Floorplan floorplan floorplan. Narrow that down and you'll find at least 10 brans/models of similar floorplan. Role play in a number of them. Sit on the toilet, lie in the beds. What can you access when all the slides are in (AKA turtled)? Two things I have learned to appreciate from my TT are direct bathroom access and a shelf/counter right by a door that I can reach from outside. We bought our TT when kids were 1/2/5. We had many stops along the sides of roads for emergency potty breaks either right after passing a rest area or in the middle of corn fields.
You have access to several dealers in IN/OH/MI with some of the lowest pricing in the country. All of your choices should come in under $30k OTD. $40k MSRP turns into $26-27k selling price, tax, title, WDH, brake controller gets you under $30k. Check out Holman RV, Lakeshore RV, and RV Wholesalers for large volume highly discounted prices.
