Questions to answer:
1. Drivable or towable toy hauler? Go visit a campground, find some campers with both types, pull up a chair and commence the conversation. You will hear both sides. RVers LOVE to talk about their rigs and they will tell you the good and the bad. To find RVers with toy haulers, you may have to go to a motorcycle rally or to an off-road riding area.
Towable is usually cheaper but more complicated to unhook/set up and break down/hook up in the campground than a drivable.
2. Do you want a bed available without having to unload the trike? If so, this will likely put you into the range of a 25 ft. box for the camper. This is getting into the weight range that may put up a caution flag.
3. If towable, the choice of the tow vehicle, also known as the "TV", is critical. MANY toy hauler owners buy campers that have such a heavy tongue weight that they exceed the load weight ratings of their trucks. If you already have a "half ton" pickup truck and plan to use that, you will have to be VERY particular in choosing a towable toy hauler. First step is to look at the tire loading sticker on the edge of the truck door and find the maximum allowable weight of the cargo and passengers printed there.
4. A Tri Glide (not the Ultra) is 103" x 55" x 1100 lbs., 8'-7" x 4'-7", so most toy haulers should be able to accommodate that.
