Our decision to buy a fifth wheel toy hauler over a class A diesel pusher was primarily economic precipitated by weight. Bringing Lucile (our 2017 Indian Roadmaster) was a MUST.
Lucile weighs about 950lbs with fuel. Since we didn't want to deal with a trailer (and we wanted to flat tow a daily driver), we were looking at lift systems (like Hydralift). When you do the math on a 950lbs motorcycle plus a 400lb lift and factor in leverage based on the average distance from the rear axle to the bumper, it adds around 2000lbs to the rear axle. That put us in tag-axle territory, which starts getting WAY up in price. So, we had a choice between waiting another year to save more money , or investigating a plan B. So, we started looking at toy hauler options. The only Class A toy hauler we found was a Gas model by Thor. Nope.
Then we found fifth wheels! The more we looked at fifth wheel toy haulers the more we realized that, perhaps, it should have been our Plan A all along. A lot more living space when converting the garage to an office / guest suite, two full baths, kitchen with island, etc. And the financial aspect fit too. Class A option: Roughly $300K rig (tag axle) plus $30K daily driver plus around $10K for the lift, braking system, tow system, etc ($350K minimum). Fiver Toy Hauler option: $60K Truck plus $90K rig ($150K) AND we get more living space. That was an option we could fit in our budget and timeline. We've not regretted it a bit!
