Are we talking bicycles or motorcycles?
Obviously, bicycles you load by picking it up and carrying, motorcycles, which *I* am equipped to load since Moby has a Maxon hydraulic lift installed (similar to a Tommy Gate), require a little more of a plan.
Equally obvious, ramp loading can be *interesting* at the best of times. Throw in wet conditions (if not outright rain), and/or when alcohol is involved, then hilarity and possibly danger are almost guaranteed. Just saying.
Anyway, one of the schemes I gave serious thought to was using DC-powered screw jacks (four) so the bed lives overhead. Basically, I didn't want to give up floor space for something only used 1/3 of the day.
Or alternatively, a Murphy bed was considered. But in the end, we opted for a rather nice air mattress. Added to which, Moby (large, white, like Melville wrote about) is what's called a hotshot. Think big rig with sleeper cab meets 24' local delivery truck for a hot night of monkey sex. A hotshot is the lovechild that result. So, this means our Freightliner chassis is equipped with a dog house so it has bunk beds, already (think grandsons added to the adventure).
Anyway, because I've read (above) of removing seats and front wheels so I am suspecting bicycles is what some folks have in mind. Me? A motorcycle makes for ready transportation if the rig breaks down and for local transport and doesn't involved towing a car or jeep (as I often see being done). Since I own a girlie Harley already, wheeling it in and out, plus strapping it down for transport, were considerations. Note; otherwise it lives outside while we're at an event (meaning how we deal with it not being underfoot during the day or at night). If stolen, we have insurance for a reason. Also, including a bicycle is easy enough, if a need presents (but wife doesn't do bicycles at all, and motorcycles *only* in an emergency).
Minor point being, the Harley is really only for me, or in the event of breakdown for a short trip to maybe grab a hotel while mechanics make repairs since living in the rig whilst broken down on the side of an interstate (what with the constant rocking of traffic going by) is not high on my list of things I wish to experience for more than maybe 10-minutes, and certainly not for a day or three if you catch my drift.
After all, one thing to go camping, another thing altogether would be doing it on the side of a busy thoroughfare! So speaking of breakdowns, one especially nice thing about a Freightliner-based rig like ours is this; in a country like ours, one absolutely dominated by 18-wheelers (versus diesel pushers and bus-based solutions) this means obtaining mechanics and repair parts is an order of magnitude easier (and thus, cheaper). Of course, I'm only talking about in the event of breakdown whilst on the road.
Anyway, *my* build makes no pretense whatsoever of simulating a commercial motor home. E.g. instead of all the comforts of home, it's quite simply outfitted for it's primary purpose - temporary living quarters. This, because I fly model airplanes so the use is purely short term versus full-timing. For model airplane events, substitute attending motocross races, desert racing, NASCAR racing events, going to Moab for some rock crawling, or whatever your interests are - if - they don't include back to nature and being in the middle of nowhere.
And no, I am absolutely *not* pooh-poohing those for whom middle of nowhere is the goal, just explaining why for me, the rig is primitive. Honestly, if the need present, I could - if I had to - live under a rock for two or three days. Moby is better than a rock, or even a tent!
Meanwhile, at best, Moby can be charitably described as *a small step above a pup tent* and based on photos, some of you take these things quite seriously. And note; while Moby meets the technical definition required by my county for a motor home tag (the usual, e.g. lighting, cooking, power, bathroom, and sleeping arrangement) my being (per my Dad whilst growing up), a wannabe guardhouse lawyer means;
- Toilet requirements are met with a Loveable-Loo, and
- Showering is a full size shower with 175 gallons (gray water only), and
- Thus, zero blackwater handling, e.g. kitty litter (dispose of a bag, and
- Cooking is met with a microwave (on site food vendors, or fast food)
- Refrigeration is a dorm-type 110 via converter
- Power is an onboard diesel (6KW Rigmaster) tied into main tanks, and
- Is also met with six solar panels and two packs from a Mach-E, and
- Cooling (comfort is important) is via 19kBTU via high SEER split
Re: motorcycle transport, I have a 24' Featherlite and it has these loop thingies bolted to the floor expressly for toting motorcycles. Basically (drop down bottom hinged rear door), and you just wheel it in, compress the forks, strap it down tight . . . and Bob's your uncle. Don't see why this can't be done with a bus and you're ready to go with it safely ensconced! Ramp that's four feet wide is surely bound to be easier than store bought, types.
Last thing; don't dismiss the idea of four screw jacks out of hand. This was the leading candidate until I realized a $100 air mattress would do well enough and in the event of failure, I'm just a Walmart run from replacement. However, I'm an engineer and amongst my enterprises is a machine shop. So fabricating this from 5/8 threaded rod (readily available in 10' sticks) and cheapo DC motors sourced off eBay plus bearings may be outside your wheelhouse, but not mine. Also, as usual, when you can't make it, but it so money solves everything.
Real point being, if you've never considered one of these air mattresses, you owe it to yourself to explore the possibilities. Ours has an air pump that will keep it inflated automatically, and doubles as the tool for emptying it with alacrity (5 minutes, max). Since it runs off a wall wart, the pump is actually DC based (if I were ever in a pinch).
