Hey Rob's Dually...I read your question with interest as truck bodies and equipment have been my livelyhood for over 45 years. Given what you said about the skills level and tools your best bet by far is to buy a quality pick up hoist. Quality is the key word here because everyone who gets price-sucked by N-H stuff ends up regretting it just like Harbor Freight crappo tools.
Send me a private e-mail and I'll help you out.
