Slow your roll. Don't plan to buy anything for about 9 months. Now is the time to start educating yourself before you make a big mistake.
Have you been camping before in an TT?
Do you know how big of a TT you realistically need/want?
Do you know exactly how you will be using it? (campgrounds vs. boondocking and what the difference is)
Do you know what quality in a TT looks like or what it really costs?
Do you know what the limits are on your vehicle for towing?
Do you know that you can spend $5k or more on a solar system and never need it?
You'll spend many thousands for a TT and a few more thousand furnishing it, and you haven't even move out of the driveway yet. Then there's a hit to your gas mileage, campground costs, firewood, lots of maintenance, and then there's activities while your camping unless your just going to sit in the trailer. This is not a cheap hobby. This is a lifestyle you need to want to do and it costs money.
Spend your time on educating yourself before you spend your money. You can get your education the hard way but it's cheaper to spend your time first instead of spending your money first.
Start with what your vehicle can handle.
