This is my rig, fuel 287 TT it’s 38 ft long it weighs around 12500 fully loaded, has a tongue weight of 1400-1500 pounds I pull it with a19 F-350 dually 6.7 diesel my P1K-5 fits no problem top to bottom but side to side it’s a tight fit. If you are wanting a separate garage will most likely end up with a 5er. Some things to consider when buying a TH...
Will your buggy fit. Size of holding tanks, most manufacturers give you a big fresh water tank and smaller grey and black water tanks, grey and black tanks sizes are important if your dry camping... no hookups. Best thing you can do is measure your buggy height and width then go on line and search for what you think will work for you and then go and walk through them, pics are great but live and in person is best. I looked at dozens of floor plans and pics on line and would go and look at them in person and would change my mind, finally settled on the fuel 287. Like was said earlier, what’s your budget? Can you pull it with your current rig or do you need to upgrade that? Hope this helps some good luck with your choice and don’t forget to post pics.😎
