Congratulations and welcome. Make sure you get an alignment--the first mod any Thor motorhome owner should do.
Just search around tons of mods everywhere on the site. Everyone seems to be inspired by everyone on here regardless of model (e.g. most have couches and you'll find many that have replaced the couch with recliners, a new bed, standalone chairs, a dinette, etc.). So don't limit yourself looking for mods for just your unit.
The best toad is the one you like--opinions will vary greatly. Jeeps are popular as a toad.
How do you want to tow the toad? 4 down? dolly? The ultimate: a fully enclosed trailer? (then you can use a model T as a toad--why not they don't weigh much
For us: We dolly tow so we can pretty much tow anything that is front-wheel-drive. At the moment we've been towing around my C-Max Energi (which also can be towed 4 down like the other Ford Hybrids: Fusion Hybrid, Fusion Energi--for 2019 it got a 5 mile bump in EV range to a whopping
25 miles (yeah sarcasm there LOL), and Lincoln MKZ Hybrid). We've also towed my wife's Escape with the dolly.
