Have you considered renting a hybrid and TT to help make a decision which style is best for you? I realise that you are looking at 2 models now which makes me think you are ready to buy but I really think you should take your time much as you undoubtedly would for car and home purchases.
Just looking at the Forest River briefly I can say that I wouldn't want to cook in the kitchen. No counter space on both sides of the stove which makes life hard when you've a hot pot in hand. Fridge seems small for the amount of people it can sleep. None of this is of much consequence if you plan to do much of your cooking outside though.
Wondering about how many BTUs the existing A/C has and if it's really powerful enough to cool the entire space successfully especially after the the heating appliances are used in the cooking area; D/K since can't find the specs. Sleeping on a pull out bed nightly might get annoying and be uncomfy w/o modifications. Little privacy between the bunk house sleeping quarters and MBR which can impede adult conversations indoors; same problem exists w/ hybrids and tents though. Not much in the way of windows, either for viewing or cross ventilation. No skylight in the bathing area which can promote mold (if the vent system isn't up to snuff) and certainly would feel kind of creepy for those who prefer natural light in that area.
Didn't look closely at the hybrid's feature but am sure you can find pros and cons in it's layout as well. The thing is for you to look and decide what will work best for YOUR needs and usage.
HTH.
